Question

Use distributive law and evaluate : $407\times 168—307\times 168$

Answer 1

Evaluating the expression using distributive law

The given expression is $407\times 168—307\times 168$

$=168\times (407—307)[\because Distributivelaw:a\times b-a\times c=a\times (b-c\left)\right]$

$$\begin{gathered} =168\times 100 \\ =16800 \end{gathered}$$

Hence, $407\times 168—307\times 168=16800$
