Question

Find using distributive property a. 58x101 b. 72x99

Answer 1

using distributive property:-

$\fcolorbox{red}{blue}{(a). 58x101}$

$\fcolorbox{green}{red}{solution}$

$\Rightarrow 58 \times (100 + 1)$

$\Rightarrow \: 58 \times 100 + 58 \times 1$

$\Rightarrow \: 5800 + 58$

$\Rightarrow \fcolorbox{blue}{green}{ 5858}$

$\fcolorbox{grey}{red}{b. 72x99}$

$\fcolorbox{blue}{grey}{solution}$

$\Rightarrow \: 72 \times (100 - 1)$

$\Rightarrow \: 72 \times 100 - 72 \times 1$

$\Rightarrow7200 - 72$

$\Rightarrow \underline \fcolorbox{red}{blue}{7128}$
