@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.

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?

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.
?

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
