c my attachment

OpenStudy (anonymous):

Is that the final answer? I do not see that in my choices.

OpenStudy (shamim):

feel free to ask if u hv confusion

OpenStudy (shamim):

do u hv any answer

OpenStudy (anonymous):

5 -1/6 5 3/2 5 5/2 5 -5/6

OpenStudy (shamim):

i think my result is right

OpenStudy (shamim):

non of ur options is matching with my result

OpenStudy (shamim):

anyway did u understand my solution

OpenStudy (anonymous):

@phi @SolomonZelman @BSwan

OpenStudy (phi):

first write all the radicals as 5 to a fractional exponent \[ \frac{\sqrt[3]{5}\sqrt{5}} {\sqrt[3]{5^5}} \] can you do that ?

OpenStudy (phi):

for example \[ \sqrt[3]{5} = 5^{\frac{1}{3}}\]

OpenStudy (solomonzelman):

\(\Large\color{black}{ \bf \sqrt[C]{A^{B}}=A^{B/C} }\) \(\Large\color{black}{ \bf d^v \times d^c=d^{v+c} }\)

OpenStudy (phi):

then add exponents (if multiplying) and subtract exponents if dividing you will get 5 to some (fractional) exponent as the answer.

OpenStudy (anonymous):

I got 5^3/2

OpenStudy (anonymous):

so shamim was correct

OpenStudy (phi):

can you show the details ?

OpenStudy (anonymous):

He got \[3\sqrt{25}\]

OpenStudy (phi):

Jody, can you show how you got your answer?

OpenStudy (anonymous):

lol look aat the previous steps

OpenStudy (phi):

First step is write each radical as 5 to an exponent.

OpenStudy (phi):

I did 5^(⅓) two more to do.

OpenStudy (anonymous):

Shamim got it wrong confusing me

OpenStudy (phi):

can you do this write each radical as 5 to an exponent. ?

OpenStudy (anonymous):

he didnt -.-

OpenStudy (phi):

can you write \[ \sqrt{5} \] using an exponent ?

OpenStudy (dan815):

hey why do u say that

OpenStudy (dan815):

a^(x/y)*a(y/x) = a^((x^2+y^2)/yx) does not have to equal 1

OpenStudy (anonymous):

its wrong ... o_o sorry ._. .-. deleting comments

OpenStudy (anonymous):

i think game of thrones damaged my head today -.-
