Question

3√8w^2 ... Solve this.

Answer 1

What are we trying to do

Answer 2

try to solve it

Answer 3

?

Answer 4

simplify?

Answer 5

\[\sqrt[3]{8w ^{2}}\]

Answer 6

yes

Answer 7

oh ok, so what you do is that can take the W^2 out of the square root. do you know what i mean?

Answer 8

like the w^2 when you square root is w

Answer 9

2\[\sqrt[2]{8w ^{2}}\]

Answer 10

sorry, the I meant to put a 3 with the radical

Answer 11

2\[\sqrt[2]{8w ^{2}}\]

Its not sqaure root, its cubed

Answer 12

and simplifying the sqrt 8 u can rewrite as 4 times 2 under the square root then take the square root of 4 and get 2 times sqrt of 2

Answer 13

Ik I meant to put three

Answer 14

i think i got it

Answer 15

\[2w ^{\frac{ 2 }{ 3 }}\]

Answer 16

no

Answer 17

i searched in mathway, its correct

Answer 18

I also used mathway and I got different answer

Answer 19

so you have 3 times sqrt of 8w^2 right
then you can take the w out like how I told u and have 3w times sqrt of 8. You can simplify the 8 into 4 times 2 and then take the 4 out
getting 6w times sqrt 2

Answer 20

Use properties of exponents

Answer 21

your answer is right

Answer 22

my answer that i got was \[2w ^{\frac{ 2 }{ 3 }}\]

Answer 23

whose?

Answer 24

ill even snip it

Answer 25

what math is this, algebra 1?

Answer 26

well for my brother

Answer 27

yea, he needs help

Answer 28

this is your brother's problem? can't u help him then?

Answer 29

im too lazy, and i practically dont understand

Answer 30

hold up, do you understand what I did for that problem?

Answer 31

all of them?

Answer 32

Cool, that is the Rational Exponents, not simplified form, which one does it need?

Answer 33

already did 1
2: distribute the exponent that is to the power of 3 over all the individual terms, like the 8 is going to be 2, and the w^2 is going to be w^2/3 so the new eqn becomes 2(w^(2/3))

Answer 34

3: simplify the 8 like in the step above well it leads to the same answer as 2 xD

Answer 35

4) is also 3 but the 8 is rewritten so it is also the same

Answer 36

oh wait a minute, these are all steps to the same problem

Answer 37

When you realize...

Answer 38

OMG, why???
you said it was 3 times 8w^2 first not cube root

Answer 39

Where do you see that?
