Question

81 elevado a 1 sobre 2 + 27 elevado a 2 sobre 3 + 45 elevado a 0​

Answer 1

$81 {}^{ \frac{1}{2} } + 27 {}^{ \frac{2}{3} } + 45 {}^{0} = \sqrt{81} + \sqrt[3]{27 {}^{2} } + 1 = \\ \\ 9 + \sqrt[3]{3 {}^{3 {}^{2} } } + 1 = 9 + \sqrt[3]{3 {}^{6} } + 1 = \\ \\ = 9 + 3 {}^{ \frac{6}{3} } + 1 = 9 + 3 {}^{2} + 1 = 9 + 9 + 1 = \\ \\ = 19$
