1. The problem statement, all variables and given/known data let x and y be positive integers and n = x^y If n + n^(1/2) + n ^(1/3) = 76, then x cannot equal A. 64 B. 16 C. 8 D. 4 E. 2 2. Relevant equations 3. The attempt at a solution i really don't know how to approach this question. i tried simplifying the powers and write them in terms of x and y, e.g. x^y + x^(y/2) + x ^(y/3) = 76 and i expressed the answers as powers of 2 but i couldn't find a way out.
