Question

Вычислите (2√1,3) ² срочно

Answer 1

Ответ:

$= \frac{26}{5}$

Объяснение:

$(2 \sqrt{1.3}) {}^{2} = \\ = (2 \sqrt{ \frac{13}{10}} ) {}^{2} = \\ = (2 \times \frac{ \sqrt{13} }{ \sqrt{10} } ) {}^{2} = \\ = ( \frac{2 \sqrt{13} }{ \sqrt{10} } ) {}^{2} =$

$( \frac{ \sqrt{130} }{5} ) {}^{2} = \\ = \frac{130}{25} = \\ = \frac{26}{5}$
