Question

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

Answer 1

(2-5/4)^2•4/3-1/2=x/4 x=4[(2-5/4)^2•4/3-1/2]=0,25•4=1

Answer 2

$(2^{(4}-\frac{5}{4})^2:\frac{3}{4}-0,5=\frac{x}{4} \\\\ (\frac{8-5}{4})^2:\frac{3}{4}-\frac{\not5}{\not10}=\frac{x}{4} \\\\ (\frac{3}{4})^2*\frac{4}{3}-\frac{1}{2}=\frac{x}{4} \\\\ \frac{9}{\not16}* \frac{\not4}{3} -\frac{1}{2}=\frac{x}{4} \\\\ \frac{\not 9}{4}*\frac{1}{\not 3}-\frac{1}{2}=\frac{x}{4} \\\\ \frac{3}{4}-\frac{1}{2}^{(2}=\frac{x}{4} \\\\ \frac{3-2}{4}=\frac{x}{4} \\\\ \boxed{x=1}$
