Question

1. $(4.3 \times 10^{-2})(5.6 \times 10^{-4})$

Explanation:

Step1: Multiply the coefficients

$4.3 \times 5.6 = 24.08$

Step2: Multiply the powers of 10

$10^{-2} \times 10^{-4} = 10^{-2 + (-4)} = 10^{-6}$

Step3: Combine and adjust to scientific notation

$24.08 \times 10^{-6} = 2.408 \times 10^{-5}$

Answer:

$2.408 \times 10^{-5}$
