The "common denominator" is 4R so you have 4v/(4R)- R/(4R)= (4v- R)/(4R)= 1/n^2. Now take the reciprocal of both sides: 4R/(4v- R)= n^2. Finally, just take the square root of both sides.
Now and then multiply both sides by ... Then divide both sides by ... Then take the square root of each side to get...
