Question

calcule as potências​

Answer 1

Explicação passo-a-passo:

a)

${2}^{3} = 2 \times 2 \times 2 = 8$

b)

${16}^{0} = 1$

c)

${( - 4)}^{3} = ( - 4) \times ( - 4) \times ( - 4) = - 64$

d)

$( - 5) {}^{ - 2} = ( - \frac{1}{5} ) {}^{2} = ( \frac{1}{5} ) \times ( \frac{1}{5} ) = \frac{1}{25}$

e)

${4}^{ - 4} = ( \frac{1}{4} ) {}^{4} = ( \frac{1}{4} ) \times ( \frac{1}{4} ) \times ( \frac{1}{4} ) \times ( \frac{1}{4} ) = \frac{1}{256}$
