Me with this question!
thx in advance

The answer for this question is quite simple. It lies between finding out the squares of a given numbered value.

In this case, a squaring of a number is meaning to multiply the number two times. So: 2^2 would yield 2 × 2 = 4, 3^2 would yield 3 × 3 = 9, 4^2 would yield 4 × 4 = 16, and so on. Here, 4 is squared and added by 25. So:











Hope it helps.
