SIMPLIFY THE EXPRESSION

OpenStudy (anonymous):

\[\sqrt{39(\sqrt{6+7)}}\]

OpenStudy (fibonaccichick666):

so do you remember your order of operations?

OpenStudy (anonymous):

no

OpenStudy (anonymous):

or do i got to find out what x what = 39?

OpenStudy (fibonaccichick666):

alright that is what you need to use here. please read this to review the order of operations http://www.purplemath.com/modules/orderops.htm

OpenStudy (fibonaccichick666):

I do not understand your second statement

OpenStudy (anonymous):

i dont get this i havent done math in over 10years

OpenStudy (anonymous):

im willing to learn

OpenStudy (fibonaccichick666):

ok, (I apologize if this seems offensive) did you read the webpage?

OpenStudy (anonymous):

let me AGAIN its not offensive i dont even think i ever learn this in school and i never got math anyway i suck at it im ok with that but atleast im willing to learn

OpenStudy (fibonaccichick666):

Ok, I'm willing to teach if you are willing to learn, so long as you are willing to put in the effort which I can tell you are.

OpenStudy (anonymous):

\[3\sqrt{26}+7\sqrt{39}\]

OpenStudy (anonymous):

ok im still drawing a blank

OpenStudy (fibonaccichick666):

it's ok. So let's start with an easier problem \[\sqrt{6+7}=?\]

OpenStudy (anonymous):

13

OpenStudy (fibonaccichick666):

are you certain you didn't forget anything?

OpenStudy (anonymous):

4 + 32 = 4 + 9 = 13

OpenStudy (anonymous):

no?

OpenStudy (fibonaccichick666):

no, ok. I really don't know how you came up with that eq. So I'll give you a fact so you can try again, You have to do the operation under the radical first. You cannot distribute the radical when you are adding something.

OpenStudy (fibonaccichick666):

I do appreciate you trying :)

OpenStudy (anonymous):

thanks

OpenStudy (anonymous):

i appreciate the help im trying to get my high school diploma because i really want to go to college

OpenStudy (fibonaccichick666):

That is an impressive and admirable goal.

OpenStudy (anonymous):

yeah my mom passed in jan so i take care of my dad and i have a 5yr old

OpenStudy (fibonaccichick666):

That's hard. I'm sorry for your loss.

OpenStudy (anonymous):

yes it is hard i miss my mom very much and ive been threw some other really messed up stuff too so im just trying to start new and fresh

OpenStudy (anonymous):

thank you

OpenStudy (fibonaccichick666):

ok, so I'm willing to help with math and proofread if you wish. I'm decent at some other subjects, but those are my specialties

OpenStudy (anonymous):

aw thanks!

OpenStudy (fibonaccichick666):

ok? So let's give this one a try

OpenStudy (anonymous):

so far ive gottan b's in 3 other classes and a c in algebra 1

OpenStudy (anonymous):

ok ready

OpenStudy (fibonaccichick666):

So the first thing I want to review is order of operations.

OpenStudy (fibonaccichick666):

and what a radical is

OpenStudy (fibonaccichick666):

So the order of operations is the rules for how we do everything in math. It is a pivotal concept to learn in order to use any math or take any class.

OpenStudy (fibonaccichick666):

There are many acronyms to assist with this. My favorite is \(\color{red} Please~\color{red} Excuse~\color{red}My~\color{red}Dear~\color{red}Aunt~\color{red}Sally\)

OpenStudy (fibonaccichick666):

The P stands for Parentheses. That is the first thing that you have to do. Anything under a radical is technically in parentheses. Do you follow?

OpenStudy (anonymous):

yes

OpenStudy (fibonaccichick666):

Next up is E it stands for exponents. Any radical can be written as an exponents and the rules for exponents apply. eg. \(√2=2^\frac{1}{2}\)

OpenStudy (fibonaccichick666):

M is for multiplication, D is for division

OpenStudy (fibonaccichick666):

there are a few properties that both of these have that can be covered in more detail later

OpenStudy (fibonaccichick666):

A is for addition, S is for subtraction
