A square has a factor that multiplies by itself to get that number.
suppose the n has the prime factorization of x*y. We know that every unique integer has a unique prime factorization. n*n = (x*y)*(x*y) = x^2*y^2.
They are called square numbers because they can form a square and the square is one number times itself.
no because 25 is one and so is 36 and it can't be in between or it's not a square number.
