Question

calcular as potencias ​

Answer 1

Olá! Tudo bem com você?

Então, vamos lá!

$1-a) 4^{-2} = \frac{1}{16} \\b) 4^{-3} = \frac{1}{64}\\c) 5^{-1} = \frac{1}{5} \\d) 3^{-3} = \frac{1}{27}\\e) 10^{-2} = \frac{1}{100}\\f) 10^{-3} = \frac{1}{1000}\\g) 2^{-5} = \frac{1}{32}\\h) 7^{-1} = \frac{1}{7}\\i) 1^{-18} = \frac{1}{1} = 1$

$2-a) (-5)^{-2} = \frac{1}{25} \\b) (-3)^{-4} = \frac{1}{81}\\c) -2^{-} = \frac{1}{-32} \\d) -5^{-3} = \frac{1}{-125}\\e) -1^{-4} = \frac{1}{1}\\f) -1^{-5} = \frac{1}{-1}$

Espero ter ajudado,

bons estudos!
