Answer 1

Answer:

a) Express 4 and 8 as products of 2 then use exponents.

4 × 8 = (2 × 2) × (2 × 2 × 2) = 2 × 2 × 2 × 2 × 2 = 2 5

b) Express 25 as products of 5 then use exponents.

25 × 5 = (5 × 5) × 5 = 5 × 5 × 5 = 5 3

c) Express all terms as products of 4 then use exponents.

16 × 4 × 4 3 = (4 × 4) × 4 × (4 × 4 × 4) = 4 × 4 × 4 × 4 × 4 × 4 = 4 6

d) Express all terms as products of 2 then use exponents.

2 × 2 × 8 × 2 3 = 2 × 2 × (2 × 2 × 2) × (2 × 2 × 2) = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 = 2 8
