Simplify:$4.2\times10^2+3.8\times10^2$

Given:

$4.2\times10^2+3.8\times10^2$

To do:

We have to simplify the given expression. 

Solution:

We know that, 

$a \times b + a \times c =a\times (b+c) $

Therefore, 

$4.2\times10^2+3.8\times10^2=(4.2+3.8)\times10^2$

$=8\times10^2$

$=8\times 100$

$=800$

Hence,

$4.2\times10^2+3.8\times10^2=800$.
