Answer 1

Răspuns:

Explicație pas cu pas:

Sper ca am descifrat bine:

2/7 * 14/10 + 4/9 : 10/4 + 5^2/5^3

2/7 * 14/10 = 2/5

4/9 : 10/9 = 4/9 * 9/10 = 4/10 = 2/5

5^2/5^3 = 1/5

___________

2/5 + 2/5 + 1/5 = 5/5 = 1

Answer 2

$\it \dfrac{2}{7}\cdot\dfrac{14}{10}+\dfrac{4}{9}:\dfrac{10}{9}+\dfrac{5^2}{5^3}=\dfrac{\ 28^{(14}}{70}+\dfrac{4}{9}\cdot\dfrac{9}{10}+\dfrac{25^{(25}}{125}=\dfrac{2}{5}+\dfrac{2}{5}+\dfrac{1}{5}=\dfrac{5}{5}=1$
