Question

1. Calcule as potências​

Answer 1

Resposta:

a) =8  b) = 20   c) = 2   d) = 4/5    e) = 10    f) = 5    g) = 2   h) = 2/3

Explicação passo-a-passo:

a) $64^{\frac{1}{2} } => \sqrt{64} = 8$

b) $400^{\frac{1}{2} } => \sqrt{400} = 10$

c) $8^{\frac{2}{3} } => \sqrt[3]{8} => \sqrt[3]{2^{3} } = 2$

d) $(\frac{16}{25})^{\frac{1}{2} } => \sqrt{\frac{16}{25} } => \frac{4}{5}$

e) $100^{0,5} => 100^{\frac{1}{2}} => \sqrt{100} = 10$

f) $625^{0,25} => 625^{\frac{1}{4}} =>\sqrt[4]{625} => \sqrt[4]{5^{4} } = 5$

g) $32^{\frac{1}{5} } => \sqrt[5]{32} => \sqrt[5]{2^{5} } = 2$

h) $(\frac{8}{27})^{\frac{1}{3} } => \sqrt[3]{\frac{8}{27} } => > \sqrt[3]{\frac{2^{3} }{3^{3} } } = \frac{2}{3}$
