(10/7-5/2)×(4/1+6/5)÷6,2​

Answer 1

$(\frac{10}{7}-\frac{5}{2})(\frac{4}{1}+\frac{6}{5})\div 6,2=\frac {375}{424} \\ \\ 1) \frac{10^{(2}}{7}-\frac{5^{(7}}{2}= \frac{20}{14}-\frac{35}{14}=-\frac{15}{14}=-1\frac {1}{14} \\ \\ 2) \frac{4^{(5}}{1}+\frac{6}{5}=\frac{20}{5}+\frac{6}{5}=\frac{26}{5}=5\frac{1}{5} \\ \\ 3) \frac{25}{5} \div 6,2 = \frac{25}{5}\times\frac{10}{62}=\frac{50}{62}=\frac{25}{31} \\ \\ 4) - \frac{15}{14}\times\frac{25}{31}=\frac{375}{424}$
