The sum of a [single] square equals the square.

The integers are 7, 8 and 9.

A sum is the addition of two or more figures. For example, 2 + 7 = 9 The square of a sum can be written as (2 + 7)2 = 92 = 81 (2 + 7)2 can also be expressed as (2 + 7) x (2 + 7) When multiplying bracketed terms, multiply the first term in the first bracket by all the terms in the second bracket and then repeat this process with the second number in the first bracket. For example, (2 + 7) x (2 + 7) = 2x2 + 2x7 + 7x2 + 7x7 = 4 + 14 + 14 + 49 = 81
