a)[tex]\sqrt2 *\sqrt8=\sqrt16=4[/tex]
b)[tex]\sqrt10*\sqrt2*\sqrt5=\sqrt20*\sqrt5=\sqrt100=10[/tex]
c) [tex]\sqrt50:\sqrt2=\sqrt25=5[/tex]
d) [tex]\sqrt1000:\sqrt10=\sqrt 100=10[/tex]
e)[tex]\sqrt 6^{5} :\sqrt 6^{3}=\sqrt 6^{2}=6[/tex]
f)[tex]\sqrt64:\sqrt2^{3} :\sqrt2=8:\sqrt2^{3}:\sqrt2=8:\sqrt2^{3}*\frac{1}\sqrt{2}[/tex]
[tex]\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[/tex]
g) [tex]\sqrt{5^{3} } :\sqrt{5} =\sqrt{5^{2} }=5[/tex]
h)[tex]\sqrt{18}:\sqrt{2} =\sqrt{9}=3[/tex]
i)[tex]\sqrt{2}*\sqrt{32} =\sqrt64} =8[/tex]
