Question

Using the distributive property of multiplication over addition/subtraction of whole numbers, find each of the following product.

$835x104$

Answer 1

The given expression is $835x104$

$\begin{array}{rcl}835x104& =& 835\times (100+4)\\ & =& 835\times 100+835\times 4[\because a\times (b+c)=a\times b+a\times c]\\ & =& 83500+3340\\ & =& 86840\end{array}$

Hence, the product of $835x104$ is $86840$.
