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.
