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)
$sqrt{ {( - 0.5)}^{6} } = {( - 0.5)}^{3} = - 0.125$
