Your answer :

(5²)(5⁴) = 5⁶ (1²)(1³) = 1⁵ = 1 8² = 64 (3²)(3²) = 81 ⎫⎬⎭ This set contains a mistake.

Let’s see:

(5²)(5⁴) = 5^(2 + 4) = 5⁶; 8² = 8 × 8 = 64; (1²)(1³) = 1^(2 + 3) = 1⁵ = 1 × 1 × 1 × 1 × 1 = 1; (3²)(3²) = 3^(2 + 2) = 3⁴ = 3 × 3 × 3 × 3 = 81.

These are all correct. Return to Page 63 and choose another answer.
