Question

(2-5/4)la puterea 2:3/4-0,5-1/4=

​

Answer 1

$( \frac{2 - 5}{4} )^{2} \div \frac{3}{4} - \frac{0.5 - 1}{4}$

$( \frac{ - 3}{4} ) ^{2} \div \frac{3}{4} - \frac{ - 0.5}{4}$

$\frac{9}{16} \times \frac{4}{3} - ( - \frac{5}{10} \times \frac{1}{4} )$

$\frac{3}{4} + \frac{5}{40}$

amplificam prima fractie cu 10

$\frac{30 + 5}{40}$

$\frac{35}{40}$

simplificam cu 5

$\frac{7}{8}$
