Question

PLEASEE help me with this !!!!!!! Write your answer in simplest radical form.

Answer 1

\[-2\sqrt[3]{11} - (-8\sqrt[4]{3}) -(-8\sqrt[4]{3}) +15\sqrt[3]{11} \]
Start by combining like terms.

Answer 2

SO would you combine the first number with the last

Answer 3

Yes. the first and last terms are like terms. To make it easier for you to type, use x for \(\sqrt[3]{11}\) and y for \(\sqrt[4]{3}\)

Answer 4

okayyy

Answer 5

do i find the sqrt of x ?

Answer 6

No, the instructions are to simplify not to evaluate. Simplest radical form means that your answer will still contain radicals.

Answer 7

ohh okay i understand that. so this is the answer ? 2√11 and 4√3

Answer 8

Not sure how you came up with that, but I found a mistake in my equation. I'll fix it here.
\[-2\sqrt[3]{11} - (-8\sqrt[4]{3}) -8\sqrt[4]{3} +15\sqrt[3]{11}\]
Now it matches what was on your image.

Answer 9

Note that two negatives make a positive.

Answer 10

well how are u just supposed to simplify this ?

Answer 11

As you stated before, the first and last terms are like terms, combine them.

Answer 12

Just the same way as if the equation read:
\[-2x-(-8y)-8y+15x\]

Answer 13

soo do i add them ? -2 and the 15

Answer 14

yes.

Answer 15

okk and then what do i do with the 2 & 11

Answer 16

do you mean \(\sqrt[3]{11}\)?

Answer 17

yesssss

Answer 18

Nothing. You just place the correct coefficient in front of it. Treat it the same as you would a variable.

Answer 19

Are there any more like terms to combine?

Answer 20

sooo it would be 13 2√11

Answer 21

Yes.

Answer 22

now we have to combine y

Answer 23

Yes.

Answer 24

-16 4√3

Answer 25

Try again. remember that a negative times a negative equals a positive.

Answer 26

64 ?

Answer 27

is this correct

Answer 28

When there is no coefficient, it is assumed to be 1.
\[-(-8) = +8\]

Answer 29

16

Answer 30

-8 +8 = ?

Answer 31

0

Answer 32

right.

Answer 33

So, when you combine those terms, what do you get?

Answer 34

idk im lost right now

Answer 35

4√0

Answer 36

OK. You started here:
\[-2\sqrt[3]{11} - (-8\sqrt[4]{3}) -8\sqrt[4]{3} +15\sqrt[3]{11}\]
You combined the first and last terms to get:
\[13\sqrt[3]{11} - (-8\sqrt[4]{3}) -8\sqrt[4]{3}\]
Now, you have a distribution to do. Do you see it?

Answer 37

you distribute the y ?

Answer 38

It is the -1.
\[-(-8\sqrt[4]{3}) = -1 \times -8\sqrt[4]{3}\]
Do you see it?

Answer 39

where did you get -1 ?

Answer 40

It is implied with the - outside of the parenthesis.

Answer 41

alright

Answer 42

Does that make sense now? Can you finish the problem?

Answer 43

it makes sence where you put it but i need help putting it in simliest radical form for the answer

Answer 44

simplest

Answer 45

Can you combine those two terms?

Answer 46

Dinner time. I'll be back soon.

Answer 47

ugh

Answer 48

-8 - -8= 0??

Answer 49

yes.

Answer 50

So What does that mean for those two radicals?

Answer 51

uhmm there simplified ?

Answer 52

you there

Answer 53

Yes, I'm here.

Answer 54

ok. so am i almost done ?

Answer 55

Yes. What will you do with the last two terms.?
\[13\sqrt[3]{11} - (-8\sqrt[4]{3}) -8\sqrt[4]{3}\]

Answer 56

doesnt it become 0?

Answer 57

Yes. And now you are left with one term. That is the simplified radical.

Answer 58

13 2√11 ?? how do u write that with the long sqrt sign from a keyboard ?

Answer 59

and it won't let me copy it

Answer 60

\[13 \sqrt[3]{11}\]
That is a cube root, not a square root.
On this site, you would use this code:
13 \sqrt[3]{11}
That is LaTeX code.

Answer 61

It starts with \[

Answer 62

And ends with \]

Answer 63

To get the code for any math writing, right-click on the line and choose "show as math" ->"tex commands.

Answer 64

whats the website ?

Answer 65

To write math here you would use LaTeX. You can get help with LaTeX by typing latex cube root or whatever you are looking for.

Answer 66

where do you type this at ?

Answer 67

Any math you see here, you can right-click to get the code used to create it.
\[-2\sqrt[3]{11} - (-8\sqrt[4]{3}) -8\sqrt[4]{3} +15\sqrt[3]{11}\]
Try it above.

Answer 68

right into the reply box.

Answer 69

The code doesn't show you it.
