Resposta:

$a)~~\sqrt{\frac{9}{4} } =\sqrt{\frac{3^2}{2^2} } =\frac{3}{2} \\ \\ \\ b)~~\sqrt{\frac{49}{81} } =\sqrt{\frac{7^2}{9^2} } =\frac{7}{9} \\\\ \\ c)~~\sqrt{\frac{1}{49} } =\sqrt{\frac{1}{7^2} } =\frac{1}{7} \\\\ \\ d)~~\sqrt{\frac{36}{64} } =\sqrt{\frac{6^2}{8^2} } =\frac{6}{8} \\ \\ \\ e)~~\sqrt{\frac{100}{81} } =\sqrt{\frac{10^2}{9^2} } =\frac{10}{9} \\\\ \\ f)~~\sqrt{\frac{1}{100} } =\sqrt{\frac{1}{10^2} } =\frac{1}{10}$
