Answer 1

-19

Answer 2

To find two square numbers that subtract to make 21, we can set up the equation x^2 - y^2 = 21, where x and y are the square roots of the square numbers. This equation can be factored as (x + y)(x - y) = 21. The factors of 21 are 1, 3, 7, and 21, so we can set up different pairs of equations to solve for x and y. The solutions are x = 5 and y = 2, which means 25 - 4 = 21.

Answer 3

Oh, dude, you're hitting me with some math here? Alright, let me think for a sec... Oh, I got it! It's 25 minus 4! 25 is a square number because it's 5 times 5, and 4 is a square number because it's 2 times 2. So, 25 minus 4 equals 21. Math genius, right here!
