Explicație pas cu pas:

a)$\sqrt2 *\sqrt8=\sqrt16=4$

b)$\sqrt10*\sqrt2*\sqrt5=\sqrt20*\sqrt5=\sqrt100=10$

c) $\sqrt50:\sqrt2=\sqrt25=5$

d) $\sqrt1000:\sqrt10=\sqrt 100=10$

e)$\sqrt 6^{5} :\sqrt 6^{3}=\sqrt 6^{2}=6$

f)$\sqrt64:\sqrt2^{3} :\sqrt2=8:\sqrt2^{3}:\sqrt2=8:\sqrt2^{3}*\frac{1}\sqrt{2}$

$\frac{8}{\sqrt2^{3} } *\frac{1}{\sqrt{2} } =\frac{8}{ 2\sqrt{2} } *\frac{1}{\sqrt{2} }=\frac{4}{\sqrt{2}} *\frac{1}{\sqrt{2} }=\frac{4}{2} =2$

g) $\sqrt{5^{3} } :\sqrt{5} =\sqrt{5^{2} }=5$

h)$\sqrt{18}:\sqrt{2} =\sqrt{9}=3$

i)$\sqrt{2}*\sqrt{32} =\sqrt64} =8$
