Answer 1

Объяснение:

1.$\sqrt{64*25}=8*5=40$

$\sqrt{\frac{49}{81} }=\frac{\sqrt{49} }{\sqrt{81} }=\frac{\sqrt{7^2} }{\sqrt{9^2} }=\frac{7}{9}$

$\sqrt{\frac{4}{9}*\frac{25}{49} }=\frac{2}{3}*\frac{5}{7} =\frac{10}{21}$

$\sqrt{27}*\sqrt{3}=\sqrt{81}=9$

$\frac{\sqrt{108} }{\sqrt{3} }=\sqrt{36}=6$

$\sqrt{18*32}=\sqrt{576}=24$

2.$\sqrt{(16,4)^2}=16,4$

$\sqrt{(-1,32)^2}=1,32$

$\frac{1}{4}\sqrt{84^2}=\frac{1}{4}*84=21$

$-0,2\sqrt{(-5)^2}=-0,2*5=-1$

$\sqrt{(-3)^4*(0,1)^6*(-5)^2}=(-3)^2*0,1^3*5=3^2*(\frac{1}{10})^3*5=9*\frac{1}{1000}*5=9*\frac{1}{200}=\frac{9}{200}=0,045$
