a)
[tex] \frac{4}{ \sqrt{2} } = \frac{4 \times \sqrt{2} }{ \sqrt{2} \times \sqrt{2} } = \frac{4 \sqrt{2} }{2} = 2 \sqrt{2} [/tex]
b)
[tex] \frac{3}{2 \sqrt{2} } = \frac{3 \times \sqrt{2} }{2 \sqrt{2} \times \sqrt{2} } = \frac{3 \sqrt{2} }{2 \times 2} = \frac{3 \sqrt{2} }{4} [/tex]
c)
[tex] \frac{4}{ \sqrt{3} } = \frac{4 \times \sqrt{3} }{ \sqrt{3} \times \sqrt{3} } = \frac{4 \sqrt{3} }{3} [/tex]
