Question

Qual o valor de 4.(0,5)⁴₊√0,25 + 8₋ ²₃

Answer 1

$4.(0,5)^{4} + \sqrt{0,25} + 8^{- \frac{2}{3} } \\ \\ 4.( \frac{5}{10} )^{4}+ \sqrt{ \frac{25}{100} }+ \frac{1}{8^{ \frac{2}{3} }} \\ \\ 4.( \frac{625}{10000} )+ \frac{5}{10}+ \frac{1}{ \sqrt[3]{8^{2}} } \\ \\ 4.(0,0625)+0,5+ \frac{1}{ \sqrt[3]{64} } \\ \\0,25+0,5+ \frac{1}{4} \\ \\ 0,25+0,5+0,25 = 1$
