Question Simplify. Write in scientific notation. (9 × 10–3)2 (1 point) Responses 8.1 × 10–5 8.1 × 10 –5 81 × 10–4 81 × 10 –4 81 × 10–3 81 × 10 –3 8.1 × 10–6

Answer 1

To simplify (9 × 10^(-3))^2, we square the base (9)^2 and multiply the exponents (10^(-3))^2, which gives us 81 × 10^(-6). In scientific notation, this is written as 8.1 × 10^(-5). So the correct response is 8.1 × 10^(-5).
