a)
[tex] \frac{1}{ \sqrt{5} } = \frac{ \sqrt{5} }{5} [/tex]
b)
[tex] \frac{ 4 }{ \sqrt{11} } = \frac{4 \sqrt{11} }{11} [/tex]
c)
[tex] \frac{4}{ \sqrt{2} } = \frac{4 \sqrt{2} }{2} = 2 \sqrt{2} [/tex]
d)
[tex] \frac{6}{ \sqrt{3} } = \frac{6 \sqrt{3} }{3} = 2 \sqrt{3} [/tex]
e)
[tex] \frac{3}{2 \sqrt{7} } = \frac{3 \sqrt{7} }{2 \times 7} = \frac{3 \sqrt{7} }{14} [/tex]
f)
[tex] \frac{9}{2 \sqrt{3} } = \frac{9 \sqrt{3} }{2 \times 3} = \frac{9 \sqrt{3} }{6} = 1 \frac{3}{6} \sqrt{3} [/tex]
Myślę że pomogłem ;)
