Question

Find the value of the following using various properties of the whole numbers :

$792\times 7+792\times 3$.

Answer 1

As per the distributive property of multiplication over addition of the whole numbers, if $a,b$ and $c$ are any three whole numbers, then :

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

So, using the distributive property of multiplication over addition of the whole numbers, let us find the value of the given expression :

$792\times 7+792\times 3=792\times (7+3)$

$$\begin{gathered} =792\times 10 \\ =7920 \end{gathered}$$

Hence, the required value is $7920$.
