Question

1. solve 0.003 × 0.006

Explanation:

Step1: Convert to scientific notation

$0.003 = 3 \times 10^{-3}$, $0.006 = 6 \times 10^{-3}$

Step2: Multiply coefficients

$3 \times 6 = 18$

Step3: Multiply powers of 10

$10^{-3} \times 10^{-3} = 10^{-6}$

Step4: Combine results and adjust

$18 \times 10^{-6} = 1.8 \times 10^{-5} = 0.000018$

Answer:

$0.000018$
