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.
