Answer 2

Answer

69

Step-by-step explanation:

It’s easy to solve with a calculator. Without one, we can start with some squares that we know.

1024 = 2^10, so 32^2 = 1024

40^2 = 1600

1300 seems to fall right in the middle. Let’s check: 36^2 = 1296 (e.g. (32 + 4)^2 = 1024 + 256 + 16 = 1296 if you are good with powers of 2). So, we are aiming for 37^2.

37^2 - 1300 = 37^2 - 36^2 - 4 = 37 + 36 - 4 = 69.
