Question

5/9+4/9*3.1/6*(4/19+1. 5/38-75/76) решите найдите значение выражения

Answer 1

$\displaystyle \frac59 +\frac49 \cdot 3\, \frac 16 \cdot \bigg( \frac4{19} ^{(4}+1\, \frac5{38} ^{(2}-\frac{75}{76} \bigg) =$  $\displaystyle \frac59 +\frac49 \cdot \frac {19}6 \cdot \bigg( \frac{16}{76} +1\, \frac{10}{76} -\frac{75}{76} \bigg) =$

$\displaystyle \frac59 +\frac{76}{54} \cdot \frac{16+76+10-75}{76} =$  $\displaystyle \frac59 +\frac{76}{27\cdot 2} \cdot \frac{27}{76} =\frac59 ^{(2} +\frac12 ^{(9} =$

$\displaystyle \frac{10+9}{18} =\frac{19}{18} =1\, \frac{1}{18}$

ответ: $\displaystyle \tt 1\, \frac{1}{18}$ .
