Question

Resolva as operações com frações:​

Answer 1

k) $(\frac{3}{6})^2=\frac{3^2}{6^2}=\frac{9}{36}=\frac{1}{4}$

l) $(\frac{2}{4})^3=\frac{2^3}{4^3}=\frac{8}{64}=\frac{1}{8}$

m) $\sqrt[3]{\frac{27}{64}}=\frac{\sqrt[3]{27}}{\sqrt[3]{64}}=\frac{3}{4}$

n) $\sqrt{\frac{100}{144}}=\frac{\sqrt{100}}{\sqrt{144}}=\frac{10}{12}=\frac{5}{6}$

o) $\sqrt{\frac{49}{81}}=\frac{\sqrt{49}}{\sqrt{81}}=\frac{7}{9}$
