Cho x =\(\frac{\left(\frac{3}{10}-\frac{4}{15}-\frac{7}{20}\right)\cdot\frac{5}{19}}{\left(\frac{1}{14}+\frac{1}{7}+\frac{3}{35}\right)\cdot\frac{-4}{3}}\)
Tính P=\(\sqrt{120\cdot x+39}\)
\(B=\frac{3+0,75-\frac{3}{19}}{\frac{5}{2}+0,625-\frac{5}{38}}\cdot\frac{15+\frac{15}{17}-\frac{15}{144}+\frac{15}{34}}{2+\frac{3}{17}-\frac{2}{144}}\)
C=\(\frac{3}{4}\cdot\frac{8}{9}\cdot\frac{15}{16}\cdot\cdot\cdot\frac{80}{81}\cdot\frac{99}{100}\)
