Answer 2

Explicație pas cu pas:

$\frac{2}{ \not7} \times \frac{ \not14}{ \not10} + \frac{4}{9} \div \frac{10}{9} + \frac{ {5}^{2} }{ {5}^{3} } = \frac{2}{5} + \frac{ \not4}{ \not9} \cdot \frac{ \not9}{ \not10} + \frac{1}{5} = \frac{2}{5} + \frac{2}{5} + \frac{1}{5} = \frac{2 + 2 + 1}{5} = \frac{5}{5} = \bf 1$
