Question

escreve na forma de potencia com expoente fracionário
a) 5√a3
b)7√x2
d) √3'7
e
​

Answer 1

Resposta:

Modelo: $\sqrt[2]{2^{3} } = 2^{\frac{3}{2} }$

a)

$\sqrt[5]{a^{3} } = a^{\frac{3}{5} }$

b)

$\sqrt[7]{x^{2} } = x^{\frac{2}{7} }$

c)

$\sqrt[3]{8^{5} } = 8^{\frac{5}{3} }$

d)

$\sqrt{3^{7} } = \sqrt[2]{3^{7} } = 3^{\frac{7}{2} }$

e)

$\sqrt{a} = \sqrt[2]{a^{1} } = a^{\frac{1}{2} }$

f)

$\sqrt{3} = \sqrt[2]{3^{1} } = 3^{\frac{1}{2} }$

g)

$\sqrt[3]{m} = \sqrt[3]{m^{1} } = m^{\frac{1}{3} }$

h)

$\sqrt{7^{2} } = \sqrt[2]{7^{2} } = 7^{\frac{2}{2} }$
