Question

1, 2 и 3 номер пожалуйста

Answer 1

1)
$\sqrt{1.44 \times 25 \times 90000} = \sqrt{1.44} \times \sqrt{25} \times \sqrt{90000} = 1.2 \times 5 \times 300 = 1800$
2)
$\frac{ \sqrt{20} }{ \sqrt{125} } = \sqrt{ \frac{20}{125} } = \sqrt{ \frac{4}{25} } = \frac{2}{5}$
3)
$\sqrt{ {( - 0.5)}^{6} } = {( - 0.5)}^{3} = - 0.125$
