Question

Resolva cada expressão a seguir.

a- 64^{\frac{1}{3}} + 81^{\frac{1}{2}} - 12
b-625^{\frac{1}{4}} - 1024^{\frac{1}{10}} + 100^{\frac{1}{2}}

Answer 1

a) $64 ^\frac{1}{3}+81^\frac{1}{2}-12 = \sqrt[3]{64} + \sqrt{81}- 12 = 4+9-12= 14-12= 2$

b)$625^\frac{1}{4} - 1024^ \frac{1}{10} + 100^ \frac{1}{2}= \sqrt[4]{625}- \sqrt[10]{1024}+ \sqrt{100} = 5-2+10 = 13$
