Explicație pas cu pas:
a)
[tex] \frac{ {}^{ \sqrt{5} )} 2}{ \sqrt{5} } = \frac{ 2\sqrt{5} }{5} \\ [/tex]
b)
[tex] \frac{ {}^{ \sqrt{11} )} 3 \sqrt{7} }{ \sqrt{11} } = \frac{3 \sqrt{77} }{11} \\ [/tex]
c)
[tex] - \frac{ {}^{ \sqrt{6} )} 1}{ \sqrt{6} } = - \frac{ \sqrt{6} }{6} \\ [/tex]
d)
[tex]\frac{0,25 \sqrt{3} }{0,5 \sqrt{5} } = \frac{ \frac{25 {}^{(25} }{100} \times \sqrt{3} }{ \frac{5 {}^{(5} }{10} \times \sqrt{5} } = \frac{ \frac{1}{4} \times \sqrt{3} }{ \frac{1}{2} \times \sqrt{5} } = \frac{ \frac{ \sqrt{3} }{4} }{ \frac{ \sqrt{5} }{2} } = \frac{ \sqrt{3} }{ \not4} \times \frac{ \not2}{ \sqrt{5} } \\ = \frac{ \sqrt{3} }{2} \times \frac{1}{ \sqrt{5} } = \frac{ {}^{ \sqrt{5} )} \sqrt{3} }{2 \sqrt{5} } = \frac{ \sqrt{15} }{2 \times 5} = \frac{ \sqrt{15} }{10} [/tex]
