Resposta:
Explicação passo-a-passo:
a)
[tex]\sqrt{169}=\sqrt{13^{2}}=13^{frac{2}{2}}=13[/tex]
b)
[tex]\sqrt[3]{125}=\sqrt[3]{5^{3}}=5^{frac{3}{3}}=5[/tex]
c)
[tex]\sqrt[6]{4^{3}}=\sqrt[6]{(2^{2})^{3}}=\sqrt[6]{2^{6}}=2^{\frac{6}{6}}=2[/tex]
d)
[tex]8^{\frac{2}{3}}=(2^{3})^{\frac{2}{3}}=2^{\frac{3.2}{3}}=2^{2}=4
