a shoe factory produces 1.81 × 104 pairs of shoes each month. estimate how many pairs of shoes the factory will produce if it maintains that rate for 10 years. (there are 1.2 × 102 months in 10 years.)

1. estimate each coefficient: 1.81 ≈ 2

1.2 ≈ 1

2. write the product: (2 × 104)(1 × 102)

the shoe factory would make approximately
×106 pairs of shoes in 10 years.
