 Excel hoar. L>Proof, not brute force!  EDIT: Figured it out with Wolfram and Hazzy's help. Set the expression equal to b. Used a ton of algebraic manipulation (moved terms around, squared both sides twice) to get rid of the sqrts, then solved for n. Got n = (b^2)/4 + 720/b^2. Plugged in integer values for b and saw which ones outputted integer n values. |
