Question

Use as potências de 10 para fazer os seguintes cálculos(60 pontos):
a)1000³:10000.0,01 =

b)(0,001)².100^4/10^8:0,001 =

Cálculos, por favor.

Answer 1

a )

$\frac{1000^3}{10000}*0,01 \\ \\ \frac{(10^3)^3}{10^{4}}*10^{-2} \\ \\ \frac{10^9*10^{-2}}{10^4} \\ \\ \frac{10^7}{10^4} \\ \\10^{3}$

b )

$\frac{(10^{-3})^2*(10^2)^4}{10^{8}:10^{-3}} }$

$\frac{10^{-6}*10^8}{10^{11}} \\ \\ \frac{10^2}{10^{11}} \\ \\10^{-9}$
