1. The problem statement, all variables and given/known data

At what speed is the magnitude of the relativistic momentum of a particle 11 times the magnitude of the nonrelativistic momentum?

2. Relevant equations

P=mv/(1-v^2/c^2)^1/2

3. The attempt at a solution

11=v/(1-v^2/c^2)^1/2?

Essentially, the question asks you to solve for v, when $$\gamma = 11$$.
