Question

4/5разделить на 2/25
(2/7)²

Answer 1

Ответ:

1) 10.

2) 4/49.

Пошаговое объяснение:

1) 4/5 : 2/25 = 4/5 * 25/2 = (4*25)/(5*2) = 100/10 = 10.

2) (2/7)² = (2²)/(7²) = 4/49.

Answer 2

$\frac{4}{5} \div \frac{2}{25} = \frac{4}{5} \times \frac{25}{2} = \frac{4 \times 25}{5 \times 2} = \frac{2 \times 5}{1} = 10$

${( \frac{2}{7} )}^{2} = \frac{ {2}^{2} }{ {7}^{2} } = \frac{4}{49}$
