Question

Calcule as expressões. a) 64 1/3+ 81 - 12 b) 10 +1° +121 1/2 ​

Answer 1

Resposta:

$64 \frac{1}{3} + 81 - 12 \\ = \\ \frac{193}{3(1)} + \frac{81}{1(3)} - \frac{12}{1(3)} \\ = \frac{193}{3} + \frac{243}{3} - \frac{36}{3} \\ = \frac{400}{3}$

$10 + {1 }^{0} + 121 \frac{1}{2} \\ = \frac{10}{1(2)} + \frac{1}{1(2)} + \frac{243}{2(1)} \\ = \frac{20}{2} + \frac{2}{2} + \frac{243}{2} \\ = \frac{265}{2}$
