Try the square roots of 1 and 6561, which are 1 and 81.
Their difference is 80 which is one less than 81. And that is the square of 9.
In fact this works whenevr the first of the two numbers is a square number. So the purpose of the question is not clear.

The word "difference" implies subtraction. The word "squares" implies a perfect square term or number. To recognize the "difference of squares" look for 2 perfect square terms, one being subtracted from the other. Ex. x2 - 16. "x" is being squared and 16 is a perfect square. They are being subtracted. Factors: (x+4)(x-4)

The number subtracted is 16 (42). The other square number is 25 (52). *If you include zero, the pair 9 (32) and 0 (02) also fits the equation.
"Perfect square" means that you square a whole number. Sometimes simply called "square" or "square number". "Difference of two squares" is the result of subtracting one such square from another. In most cases, the difference will not itself be a square.
