Question

Can anyone help with Simplfying these two equations?

(1/4) ^3/2

and

16 ^-3/2

Answer 1

note: they are not equations
(1/4)^(3/2) = 1^(3/2)/4^(3/2) = 1/4^(3/2) = 1/sqrt(4^3) = 1/sqrt(64) = 1/8 and 1/-8

Answer 2

zz is the second -1/8?

Answer 3

same thing
\[-\frac{a}{b}=\frac{-a}{b}=\frac{a}{-b}\]

Answer 4

nono, the first part has two solutions

Answer 5

There is a place for the first answer and a place for the second, what do I write in those places?

Answer 6

part2
16 ^-3/2
= 1/(16^(3/2))= 1/4^3 and 1/-4^3
so 1/64 and -1/64

Answer 7

um the positive one I guess

Answer 8

1/8

Answer 12

The second part is 1/64

Answer 13

So the first is 1/8 and the second 1/64?

Answer 14

yes
