Answer 1

Resposta:

Explicação passo-a-passo:

a) $(81)^{\frac{1}{2} = \sqrt{81}  = 9$

b) $(125)^{\frac{1}{3} = \sqrt[3]{125} = 5$

c) $(25)^{0,5} = (25)^{\frac{1}{2} = \sqrt{25}  = 5$

d) $(64)^{0,25} = (64)^{\frac{1}{4} = \sqrt[4]{64}$

e) $\sqrt[3]{\sqrt{128}} = \sqrt[6]{128} = \sqrt[6]{2^{6}.2 } = 2\sqrt[6]{2}$ 

f) $\sqrt[3]{\sqrt{\sqrt[4]{6}}} = \sqrt[24]{6}$

g) $\sqrt{12,5} . \sqrt{8} =  \sqrt{12,5 . 8} = \sqrt{100} = 10$

h) $\sqrt{45} . \sqrt{5} = \sqrt{3^{2} . 5} . \sqrt{5} = \sqrt{3^{2} } . \sqrt{5^{2} } = 3 . 5 = 15$

i) $\sqrt{150} : \sqrt{6} = \sqrt{150:6} = \sqrt{25} = 5$

j) $\sqrt{245} : \sqrt{5} = \sqrt{245:5} = \sqrt{49} = 7$
