Answer 1

$\sqrt{ \frac{144}{169} } = \frac{12}{13} \\ \sqrt{ \frac{400}{625} } = \sqrt{ \frac{16}{25} } = \frac{4}{5} \\ \\ 5. \\ a)( \frac{2}{3} {)}^{0} = 1 \\ b)( \frac{6}{3} {)}^{1} = 2 \\ c)( \frac{6}{7} {)}^{2} = \frac{36}{49} \\ d)( \frac{3}{5} {)}^{3} = \frac{27}{125} \\ e)( \frac{7}{3} {)}^{4} = \frac{2401}{81} \\ f)( \frac{5}{4} {)}^{3} = \frac{125}{64} \\ g)( \frac{1}{10} {)}^{10} = \frac{1}{ {10}^{10} } \\ h) \frac{1}{100} = 0.01 \\ \\ 6. \\ a)( \frac{1}{2} \times \frac{8}{5} - \frac{3}{5} ) = \frac{4}{5} - \frac{3}{5} = \frac{1}{5} \\ b) \frac{( \frac{1}{2} \times \frac{19}{7} ) }{ (\frac{1}{6} - \frac{1}{6} ) } = \frac{ \frac{1}{2} \times \frac{19}{7} }{0} = 0$
