Question

Calcule:
${2}^{0} =$

${5}^{1} =$

${3}^{1} =$

${( - 4)}^{ - 3}$

$\frac{ - 3}{5} - 2 =$
​

Answer 1

Resposta:

${2}^{0} = 1 \\ {5}^{1} = 5 \\ {3}^{1} = 3 \\ {( - 4)}^{ - 3} = { - 4}^{ - 3} = - \frac{1}{ {4}^{3} } = - \frac{1}{64} \\ \frac{ - 3}{5} - 2 = \frac{ - 3 - 10}{5} = - \frac{13}{5}$
