Write with positive exponents and simplify
Hello Everyone,

I need some help with this problem: 16 -3/2

I know for some this may be simple, but I have totally forgot how to do it step by step.

Thanks

Hmm, are you solving $16^{\frac{-3}{2}}$?

If so, recognize that there is a square root there...

$\sqrt{16}^{-3}$

$4^{-3}$

$\frac{1}{64}$
