Question

3/4 x √25/36 - (6/5 ÷ 12/5 + 1/4)5

Answer 1

$\frac{3}{4}$ · $\sqrt{ \frac{25}{36}$ - ($\frac{6}{5}$ ÷ $\frac{12}{5}$ + $\frac{1}{4}$) 5


= $\frac{3}{4}$ · $\frac{5}{6}$ - ( $\frac{6}{5}$ · ($\frac{5}{12}$ + ($\frac{1}{4}$) 5


= $\frac{1}{4}$ · $\frac{5}{2}$ - ( $\frac{1}{2}$ + $\frac{1}4{}$) 5

= $\frac{5}{8}$ - $\frac{3}{4}$ · 5

= $\frac{5}{8}$ - $\frac{15}{4}$

Mmc{8,4}= 8

= $\frac{5-30}{8}$

= $\frac{-25}{8}$
