Answer:

$4.2*10^{-1}$

Step-by-step explanation:

We want to simplify:

$2.1*10^{-3}\times 2*10^2$

We rewrite to get:

$2.1*2*10^2*10^{-3}\times10^2$

We now apply the laws of indices

$4.2*10^{-3+2}$

We simplify to get $4.2*10^{-1}$

We leave our final answer is scientific form.

The final answer is therefore:

$4.2*10^{-1}$
