Question

write in radical notation 81^-(3/4)
then evaluate the radical expression

Answer 1

ma'am is the question complete ?

Answer 2

\(\large(a^b)^c=a^{b*c}\)
\(\large a^{-b}=\frac{1}{a^b}\)
\(81=3*3*3*3*3=3^4\)
Using these can u do ur question @mathgirl501?

Answer 3

Aj is correct, but just to clarify things a bit more:
\[(a^b)^{\frac{ 1 }{ c }} = a^{\frac{ b }{ c }} = \sqrt[c]{a^b}\]
