Question

Agora, use expoentes negativos. Calc
a resposta na forma decimal:
a) 10 expoente -3
6) 2 expoente-4
c) (-4) expoente -2​

Answer 1

Resposta:

$10^{-3}  =\left(\frac{1}{10}\right)^{3} =\frac{1^3}{10^3} = \frac{1}{1000}\\2^{-4} =\left(\frac{1}{2}\right)^{4} = \frac{1^4}{2^4} = \frac{1}{16}\\-4^{-2} =\left(\frac{1}{-4}\right)^{2} = \frac{1^2}{-4^2} = \frac{1}{-4 \cdot -4} =\frac{1}{16}$
