• A. $$492\times{10^{-4}}$$
• B. $$4.92\times{10^{-6}}$$
• C. $$4.92\times{10^{-4}}$$
• D. $$492\times{10^{-5}}$$

Answer 1

Answer:

$$4.92\times{10^{-4}}$$

$0.04\times{0.0123}$ is equivalent to 4.92 × 10^-4.

$=\frac{4}{100}\times\frac{123}{1000}$

$=\frac{492}{1000000}$

$=492\times{10^{-6}}$

$=4.92\times{100}\times{10^{-6}}$

$=4.92\times{10^{-4}}$
