[tex] \frac{ \sqrt{ \sqrt{9} } }{ \sqrt{81} } = \frac{ \sqrt{3} }{9} [/tex]
2.
[tex] \frac{ \sqrt{ \frac{4}{16} } }{ \frac{3}{5} } = \frac{5 \times \frac{2}{4} }{3} = \frac{ \frac{5}{2} }{3} = \frac{5}{6} [/tex]
3.
[tex] \sqrt{ \frac{4}{2} \times \frac{3}{4} } = \sqrt{ \frac{12}{8} } = \sqrt{ \frac{3}{2} } = \frac{ \sqrt{6} }{2} [/tex]
4.
[tex] \sqrt{ \frac{5}{2} + \frac{3}{4} } = \sqrt{ \frac{13}{4} } = \frac{ \sqrt{13} }{2} [/tex]
5.
[tex] \frac{ \sqrt{ \frac{6}{3} \div\frac{4}{2} } }{ \sqrt{49} } = \frac{ \sqrt{1} }{ 7} = \frac{ 1 }{7} [/tex]
Espero haberte ayudado :)
Éxitos.
