Question

w=Cr^-2Solve the equation for r.

Answer 1

Okay. This is a bit outside of the intuitive zone.
Starting off, we will divide both sides of the equation by C.
This gives us:
w/C = r^-2
But r^-2 is the same as 1/r^2
So we have the following equation:
w/C = 1/r^2
If we reciprocate both sides of the equation, we have:
C/w = r^2
Take the square root of both sides, and you have:
sqrt(C/w) = r
