Evaluating Operations with Scientific Notation

What scientific value for n will make this equation true?
(4.8 × 10–3)(n) = 9.6 × 109

2.0 × 10–6

2.0 × 10–3

2.0 × 103

2.0 × 1012

Answer 1

Compute n = (9.6×10^9) / (4.8×10^−3).

9.6 ÷ 4.8 = 2 and 10^(9 − (−3)) = 10^12, so n = 2 × 10^12.

Answer: 2.0 × 10^12.
