OpenStudy (anonymous):
the denominator in the fraction means root and the numerator means power. does that make sense?
so 4^1/2=2
OpenStudy (vshiroky):
so 1/2 16 is 8?

\[4^\frac{ 1 }{ 2 }=\sqrt{4}=2\]
OpenStudy (anonymous):
no it is not 8. what is the square root of 16
OpenStudy (vshiroky):
4
OpenStudy (anonymous):
so then take the 5th root of 32. then square it
OpenStudy (vshiroky):
I don't understand what that means

\[(\sqrt[5]{32})^2\]
OpenStudy (vshiroky):
28^2?
OpenStudy (anonymous):
no. how did you get 28 for the 5th root of 32.
OpenStudy (vshiroky):
I have no clue!
OpenStudy (vshiroky):
That's what the calculator said.

what can you multiply by itself 5 times to get 32. just do it with 4,3,2,1 see what you get with these 4
OpenStudy (vshiroky):
Or 5.7^2?
OpenStudy (anonymous):
no
OpenStudy (vshiroky):
2
OpenStudy (anonymous):
yes that is the 5th root of 32. now you should be able to square that value and solve

4+2=6?
OpenStudy (anonymous):
no. because you have to square the 2
OpenStudy (vshiroky):
I did the first 2
OpenStudy (anonymous):
the square root of 16 isnt 2
OpenStudy (vshiroky):
8 is the answer
