Your answer :
103 = 1000
(bm)(b4) = b(m + 4)
(42)(41) = 64
(84)(86) = 810
⎫⎬⎭ This set contains a mistake.
Let’s see:
103
= 10 × 10 × 10 = 1000;
(42)(41)
= 4(2 + 1) = 43 = 4 × 4 × 4 = 64;
(bm)(b4)
= b(m + 4) (Note exponents are added);
(84)(86)
= 8(4 + 6) = 810.
They’re all correct. Return to Page 63 and choose another answer.
