The value of $\frac{0.00001 \times(0.01)^{2} \times 1000}{0.001}$ is:
(a) $10^{-1}$
(b) $10^{-2}$
(c) $10^{-3}$
(d) $10^{-4}$
(e) 1
We have:

$$
\begin{aligned}
\frac{0.00001 \times(0.01)^{2} \times 1000}{0.001} & =\frac{10^{-5} \times\left(10^{-2}\right)^{2} \times 10^{3}}{10^{-3}}=\frac{10^{-5} \times 10^{-4} \times 10^{3}}{10^{-3}}= \\
& =\frac{10^{-5+(-4)+3}}{10^{-3}}=\frac{10^{-6}}{10^{-3}}=10^{-6-(-3)}=10^{-3}
\end{aligned}
$$

The correct option is (c).
