Problem
\( \left(3 \times 10^{2}\right) \times\left(2 \times 10^{-4}\right)= \)
Solution
Step 1 ：\( (3 \times 10^{2}) \times (2 \times 10^{-4}) = (3 \times 2) \times (10^{2} \times 10^{-4}) \)
Step 2 ：\( (3 \times 2) \times (10^{2} \times 10^{-4}) = 6 \times 10^{-2} \)
Step 3 ：\( 6 \times 10^{-2} = 0.06 \)
