Question 983749: I am currently working on a summer homework packet for my Pre-Calculus class and there is a problem I have come across that I have completely forgotten how to solve. I have tried looking for example problems similar to it but to no avail. I have a picture of it written out and I would appreciate any help I could get on it. Thanks!

f%28s%29=root%283%2C30%2Fv%29+
to solve for v, first raise both sides to the power of 3 to eliminate root
%28f%28s%29%5E3%29=%28root%283%2C30%2Fv%29%29%5E3+
%28f%28s%29%5E3%29=30%2Fv+
%28f%28s%29%5E3%29%2Av=30+
v=30%2F%28f%28s%29%5E3%29+
