Question

2 1/4x(2/3)elevado al cubo+1 3/7 entre 20/21-3/4x4 raíz 16/81

Answer 1

Explicación paso a paso:

=$\frac{2\frac{1}{4}\times \left(\frac{2}{3}\right)^2+1\frac{3}{7}}{\frac{20}{21}-\frac{3}{4}\times \:4\sqrt{\frac{16}{81}}}$

=$\frac{\frac{9}{4}\times \left(\frac{2}{3}\right)^2+1\frac{3}{7}}{\frac{20}{21}-\frac{3}{4}\times \:4\sqrt{\frac{16}{81}}}$

=$\frac{\frac{9}{4}\times \left(\frac{2}{3}\right)^2+\frac{10}{7}}{\frac{20}{21}-\frac{3}{4}\times \:4\sqrt{\frac{16}{81}}}$

=$\frac{\left(\frac{2}{3}\right)^2\frac{9}{4}+\frac{10}{7}}{\frac{20}{21}-\frac{4}{3}}$

=$\frac{1+\frac{10}{7}}{\frac{20}{21}-\frac{4}{3}}$

=$\frac{1+\frac{10}{7}}{-\frac{8}{21}}$

=$\frac{\frac{17}{7}}{-\frac{8}{21}}$

=$-\frac{\frac{17}{7}}{\frac{8}{21}}$

=$-\frac{17\times \:21}{7\times \:8}$

=$-\frac{17\times \:21}{56}$

=$-\frac{357}{56}$

=$-\frac{51}{8}$=$-6\frac{3}{8}$
