[tex] \sqrt{ \frac{625}{81} } = \frac{25}{9} [/tex]
[tex] \sqrt{ \frac{25}{9} } = \frac{5}{3} [/tex]
[tex]3 \frac{1}{3} = \frac{10}{3} [/tex]
[tex] \sqrt{1.(7)} = \sqrt{ \frac{16}{9} } = \frac{4}{3} [/tex]
[tex] \sqrt{36} = 6[/tex]
[tex] \sqrt{ {6}^{4} } = {6}^{2} = 36[/tex]
[tex] \frac{25}{9} \times \frac{3}{5} + \frac{10}{3} \times \frac{3}{4} - \frac{1}{6} = \frac{5}{3} + \frac{5}{2} - \frac{1}{6} = \frac{(10 + 15 - 1)}{6} = \frac{24}{6} = 4[/tex]
