Help(hold on I'm typing it)

ThisGirlPretty:

Francisco and Ryan are stuck simplifying radical expressions. Francisco has simplified to \[X \frac{ 1 }{ 2 }/ X/\frac{3}{18} \]. Ryan has simplified to \[27\sqrt{x^2}\times{x^3}\times{x^4}.\] Using full sentences, describe how to fully simplify Francisco and Ryan's expressions. Describe if Francisco and Ryan started with equivalent expressions or if they started with expressions that are not equal.

psirockin3:

oop... LaTex. Can't.

ThisGirlPretty:

The X^2 X X^3 X X^4 are in square root

psirockin3:

Oh okay gotcha

ThisGirlPretty:

XD

Hero:

I'm still trying to process the first expression you posted.

Hero:

What exactly does \(X \dfrac{ 1 }{ 2 }/ X/\dfrac{3}{18}\) mean?

Hero:

I've never seen that notation before @ThisGirlPretty

ThisGirlPretty:

I Typed it wrong sorry lol hold on I'll take a picture

ThisGirlPretty:

have to use iPad rn

Hero:

\(\dfrac{x^\dfrac{1}{2}}{x^\dfrac{3}{18}}\)

Hero:

I don't know why that took so long to load.

ThisGirlPretty:

Yes ^ lol I didn't know how to write that o.o or say it

Hero:

`\(\dfrac{x^\dfrac{1}{2}}{x^\dfrac{3}{18}}\)`

ThisGirlPretty:

So much coding o.o

Hero:

You'll get used to it. It helped to click that equation button though.

ThisGirlPretty:

True :O

Hero:

Okay, so fractional exponents can be converted to root form by way of the following formula: \(x^\dfrac{a}{b}=\sqrt{a}\)

ThisGirlPretty:

o.o?

Ultrilliam:

uh

Ultrilliam:

hero be careful, it looks like you ended up with a bbtag there

Ultrilliam:

[ b ] or bold to be exact

Hero:

No, it was working perfectly. It's your glitches that's messing everything up

Ultrilliam:

\(x^\dfrac{a}{b}=\sqrt[ b ]{a}\)

Hero:

Okay, so fractional exponents can be converted to root form by way of the following formula: \(x^\dfrac{a}{b}=\sqrt{a}\)

psirockin3:

Nope, it looks like there's a bold segment on mine. But then again, I can't see LaTex so it might be a graphical glitch

Ultrilliam:

add those spaces in between those brackets to fix the issue

Hero:

That's exactly what I posted before. You guys are making me look bad.

Ultrilliam:

take a closer look, the [ b ] is missing

Hero:

No, you don't understand. What I just posted that DID render, all I did was copy and paste. And it rendered this time.

Hero:

I just copied and pasted the exact same thing I posted before that didn't render and it rendered this time. This is hilarious

Ultrilliam:

because it was missing the b tag because that is rendered server side

Hero:

You can check it if you want. I assure you it is the same.

Ultrilliam:

Ultrilliam:

notice the b missing?

Ultrilliam:

remind me to add a nobbcode tag to the bbcode system so conflicts like this don't happen again

Hero:

You need to add way more than just that. There's all kind of latex code not working here.

ThisGirlPretty:

Ok

Hero:

Okay, so just to clarify to everyone, I did type the correct expression, but as a result of a coding conflict, it did not render as expected.

Hero:

I will continue explaining how to solve the math problem posted by @ThisGirlPretty

ThisGirlPretty:

Ok

Hero:

Okay, so fractional exponents can be converted to root form by way of the following formula: \(x^\dfrac{a}{b}=\sqrt{a}\)

Hero:

There's the evidence that I typed the LaTeX correctly, but it renders something else because @Ultrilliam has another coding system embedded within the sever that conflicts with LaTeX.

Hero:

So I'll continue when @Ultrilliam fixes that.

Ultrilliam:

for heavens sake...

ThisGirlPretty:

XD

Hero:

Sorry, but I can't work properly in this environment unless the problem is fixed.

Hero:

This issue never occurred on OS

Ultrilliam:

[b]test

Ultrilliam:

test

Ultrilliam:

there... happy...

Hero:

Thank you. I just didn't like when you guys were trying to make me look bad earlier.

Hero:

I knew I typed it correctly the first time.

Ultrilliam:

I wasn't trying to make you look bad, I was trying to explain the situation to you.

Hero:

You said the b was missing and I knew I typed it so I knew something else was going on and I knew what I saw when I looked at the preview before it rendered so immediately knew that when what rendered and what showed up in the preview was different, I already knew a conflict existed. But you guys assumed that I didn't know what was going on. I was trying to prove to you I DID know what was going on. You just weren't hearing me.

Hero:

Anyway, let's continue:

Hero:

Okay, so fractional exponents can be converted to root form by way of the following formula: \(x^\dfrac{a}{b}=\sqrt[b]{a}\)

Hero:

So in other words, we have \(\dfrac{x^\dfrac{1}{2}}{x^\dfrac{3}{18}}\) but there is a 3/18 in the fraction portion which we will need to simplify before we continue

Hero:

@ThisGirlPretty what does 3/18 simplify to?

Hero:

Sorry for inconveniencing you with the delay btw.

ThisGirlPretty:

I don't mind and is it 0.375? :/

Hero:

Actually we don't need to simplify it to decimal. We only need to reduce it to the simplest fractional form.

Hero:

If you divide the top and bottom of 3/18 by 3, you get 1/6. Here's another way to do it:

Hero:

\(\dfrac{3}{18} \\= \dfrac{(3)(1)}{(3)(6)} \\= \dfrac{3}{3} \times \dfrac{1}{6} \\= \dfrac{1}{6}\)

ThisGirlPretty:

Ok, I understand that :D my bad

Hero:

So now what you have is \(\dfrac{x^\dfrac{1}{2}}{x^\dfrac{1}{6}}\) which converts to \(\dfrac{\sqrt[2]{x}}{\sqrt[6]{x}}\)

ThisGirlPretty:

Ok

Hero:

Hang on a minute

ThisGirlPretty:

Ok

Hero:

Okay, so this can be simplified further.

Hero:

\[\dfrac{\sqrt[2]{x}}{\sqrt[6]{x}} = \dfrac{\sqrt[2]{x}}{\sqrt[2]{x} \times\sqrt[3]{x}}=\dfrac{\sqrt{x}}{\sqrt{x}} \times \dfrac{1}{\sqrt[3]{x}}\]

ThisGirlPretty:

Okie :D

Hero:

Which simplifies to \(x^{1/3}\)

Hero:

You should review rules of exponents to get a better grasp of how to do these problems. But also, you should review how to reduce fractions. Otherwise you will have much trouble with Algebra.

ThisGirlPretty:

No matter how hard I try I will never understand math lol

Hero:

Because you don't have a personal tutor.

ThisGirlPretty:

Tbh you're right lol

Hero:

However, plenty students have learned math without tutors. You must make time to study it and you must use the right resources for what you are studying currently. And in addition to that, you must be able to consult mathematicians whenever you run into a problem.

ThisGirlPretty:

Ok, will do...how u remember all this stuff

Hero:

Practice and also knowing where to look in case you do forget.

Hero:

You must familiarize yourself with mathematics concepts. In this case, if you did get lost and you did not remember the formulas, you could google radical formulas and fractional equation formulas.

Hero:

Or rather Radical Rules or Root Rules or nth Root Rules

Hero:

If you googled any of those, you should be able to find what you're looking for.

ThisGirlPretty:

Okie dokie :p ty so much

Hero:

Another thing is, different math texts use different words and terms that mean the same thing.

Hero:

So keep that in mind.

ThisGirlPretty:

Will do
