Negative Exponents

Solve the equation w=Cr^-2
I multiplied by r^-2
wr^-2=C
Divide by w
r^-2=C/w

How do I get r by itself? I know r^-2 is 1/r^2, but that still isn't r by itself. Any help is appreciated!

Solve the equation w=Cr^-2

1st step: w = C / r^2

Thank You Denis! I think I got it then. I was over analyzing the problem.
