Question

Resolva os calculos
5⁰ - ( - 1) - ( - 2\5)²

Answer 1

$5^0-(-1)-(-\frac{2}{5})^2$

$1+1-\frac{4}{25}$

$2-\frac{4}{25}$

$\frac{50-4}{25} = \frac{46}{25}$

Answer 2

Resposta:

$5 {}^{0} - ( - 1) - ( - \frac{2}{5}) {}^{2} \\ \\ 5 {}^{0} - ( - 1) - ( - \frac{2}{5}) {}^{2} \\\\ 1 - ( - 1) - ( - \frac{2}{5}) {}^{2} \\\\ 5 {}^{0} - ( - 1) - ( - \frac{2}{5}) {}^{2} \\\\ 1 + 1 - ( - \frac{2}{5} {}^{2} \\\\ 5 {}^{0} - ( - 1) - ( - \frac{2}{5}) {}^{2} \\\\ ( - \frac{2}{5}) {}^{2} \\\\( \frac{2}{5}) {}^{2}\\\\ \frac{2 {}^{2} }{5 {}^{2} } \\ \\ \frac{4}{5 {}^{2} } \\\\ \frac{2 {}^{2} }{5 {}^{2} } \\\\ \frac{4}{25} \\ \\ 5 {}^{0} - ( - 1) - ( - \frac{2}{5}) {}^{2}\\\\ 1 + 1 - \frac{4}{25} \\ \\ 2 - \frac{4}{25} \\ \\ \frac{50 - 4}{25} \\ \\ \frac{46}{25} \\ \\ 2 - \frac{4}{25} \\ \frac{46}{25} \\\\ resposta \\\\ \frac{46}{25}$
