Question

qual é o valor de
$4 \times ( {0.5})^{4} + \sqrt{0.25} + 8 \times - \frac {2}{3}$
​

Answer 1

$2 {}^{2} \times 2 {}^{ - 4} + \sqrt{ \frac{1}{4} } - \frac{16}{3} \\ 2 {}^{ - 2} + \frac{1}{2} - \frac{16}{3} \\ \frac{1}{2 {}^{2} } + \frac{1}{2} - \frac{16}{3} \\ \frac{1}{4} + \frac{1}{2} - \frac{16}{3} \\ = \frac{55}{12}$
