c)4√3/3

d)2√3

Answer 2

a) [tex]\frac{4}{\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2} } =\frac{4\sqrt{2} }{\sqrt{2*2} } =\frac{4\sqrt{2} }{\sqrt{4} }=\frac{4\sqrt{2} }{2} =2\sqrt{2}[/tex]

b) [tex]\frac{3}{2\sqrt{2} } *\frac{\sqrt{2} }{\sqrt{2} } =\frac{3\sqrt{2} }{2*2} =\frac{3\sqrt{2} }{4}[/tex]

c) [tex]\frac{4}{\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }=\frac{4\sqrt{3} }{3 }[/tex]

d) [tex]\frac{6}{5\sqrt{3} } *\frac{\sqrt{3} }{\sqrt{3} }=\frac{6\sqrt{3} }{15 }[/tex]
