Question

What is the value of the expression (6 + 3)2
15
18
45
81

Answer 1

Probably 81.

Maybe 18.

See explanation below.

Explanation:

(6 + 3)² = 9² = 9 × 9 = 81

(6 + 3) × 2 = 9 × 2 = 18

I think you mean the first expression in which 2 is an exponent, but since it's not clear, I solved it both ways.
