Question

(x^(-5/4)*y^(1/2))^3

ohh please help.

Answer 1

You are raising the two variables to a power so you mulitply:
\[(a^{m})^{n} = a^{m*n}\]
So we have:
\[(x^{-5/4}y^{1/2})^{3}=x^{-15/4}y^{3/2}\]

Answer 2

Is that a final simplified answer?

Answer 3

15 can't be divided any more by 4. 3 can't be divided anymore by 2, so yes.

Answer 4

Thank you
