Which terms give is the perfect square of 3x4? A. 6x8 B. 6x16 C. 9x8 D. 9x16

A perfect square is the product when a number is multiplied to itself. Hence, the square of (3x4) is (3 x 4 x 3 x 4). We can rearrange this and have (3 x 3) x (4 x 4) which gives you 9 x 16. Thus, we have the perfect square of (3x4) re-written as (9 x 16). Thus, the answer is D: 9 x 16.
