Question

Solve $4^4\times \left(\frac{5}{4}\right)$

Answer 1

$4^4\times \left(\frac{5}{4}\right)$

$\Rightarrow$ $4\times 4\times 4\times 4\times \frac{5}{4}$

$\Rightarrow$ $4\times 4\times 4\times 5$

$\Rightarrow$ $64\times 5$

$\Rightarrow$ $320$

$\therefore$ $4^4\times \left(\frac{5}{4}\right)=320$
