Question

$1) 8\sqrt{20}\frac{1}{4} -\frac{\sqrt{0,36} }{\sqrt{0,01} }$
$2) \sqrt{0,64*49} - \sqrt{3x^{4}*2x^{6} }$
$3) \sqrt{18} *\sqrt{2} -\sqrt{20}* \sqrt{5}$

Answer 1

Ответ:

1) 30

Объяснение:

$8 \sqrt{20 \frac{1}{4} } - \frac{ \sqrt{0.36} }{ \sqrt{0.01} } = 8 \sqrt{ \frac{81}{4} } - \frac{0.3}{0.1} = 8 \times \frac{9}{2} - \frac{0.6}{0.1 = 36 - \frac{0.6}{0.1} } = \frac{3}{0.1} = 30$
