Best ResponseYou've already chosen the best response.0Let us take an Example: Suppose n = 4: So: Divisors are : 1, 2 and 4.. Now : \(4^2 =16\) Divisors are : 1, 2, 4, 8, 16 (5 Divisors)..

Best ResponseYou've already chosen the best response.0Oh sorry the answer is five... actually x^2 and n will be same because n has only three factors which are 1 , x and n So, n = 1*n or x*x
