What is the least number of perfect squares that sum N=12?

We can clearly see that we can reach solution in many paths but the least number of perfect squares that sums to n=12 is ps (12) = 2^2+2^2+2^2 which has 3 perfect squares. Also, note that the problem has repeating subproblems. For example, ps (2), ps (7), and ps (3) is appearing twice.

Can $N!$ be a perfect square when $n$ is an integer?

Can $n!$ be a perfect square when $n$ is an integer greater than $1$? Clearly, when $n$ is prime, $n!$ is not a perfect square because the exponent of $n$ in $n!$ is $1$. The same goes when $n-1$… Stack Exchange Network

How do you find the number of perfect square numbers?

If a number itself is a perfect square number then numbers of square is 1. Otherwise we can try break the number into 2 squares i and j such that n=i*i+j*j, for any i, 1≤i≤√n. So, for any natural positive number there are only 4 possible results: 1, 2, 3, 4.

What is an example of a perfect square?

Perfect Square: Taking a positive integer and squaring it (multiplying it by itself) equals a perfect square. Example: 3 x 3 = 9 Thus: 9 is a perfect square.
