Question

Solve w=Cr^-2 for r.
I know the r becomes 1/r^2, but I con not figure out how to get the rest of the equation.

Answer 1

r=sqrt(c/w)

Answer 2

:) \[r^{2}=C/w.....r=\sqrt{\frac{c}{w}}\]

Answer 3

s\[\S ^{-1}\rightarrow 1/\S so R ^{-2} \rightarrow 1/R ^{2}\]

Answer 4

C not included i think \[w = r ^{-2}\]

Answer 5

Thank you! I was really turned aroun on this one...
