$\displaystyle \sqrt{x} \bf -\frac{2}{3}\cdot \Big(3\frac{3}{8}-1\frac{1}{2}\Big)= -\frac{2}{3}\cdot \Big(3-1+\frac{3}{8}-\frac{1}{2}\Big)=-\frac{2}{3}\cdot \Big(2+\frac{3}{8}-\frac{4}{8}\Big)=\\\\\\=-\frac{2}{3}\cdot \Big(2+\frac{3}{8}-\frac{4}{8}\Big)=-\frac{2}{3}\cdot \Big(2-\frac{1}{8}\Big)=-\frac{2}{3}\cdot \Big(1+\frac{8}{8}-\frac{1}{8}\Big)=-\frac{2}{3}\cdot \Big(1+\frac{7}{8}\Big)=\\\\\\=-\frac{2}{3}\cdot \frac{15}{8}=-\frac{5}{4}=-1\frac{1}{4}=-1,25$
