a)10x
b)x
---
100
c)100x
d)x
e)x
------
10

Answer 1

Vamos passo a passo
 
$\frac{(0,1).(0,001).10 ^{-1} }{10(0,0001)} \\ \\= \frac{ 10^{-1} . 10^{-3}. 10^{-1} }{10. 10^{-4} } \\ \\ = \frac{ 10^{-1-3-1} }{10^{1-4} } \\ \\ = \frac{ 10^{-5} }{ 10^{-3} } \\ \\ = \frac{10^3}{10^3.10^2} \\ \\ = \frac{x}{x.10^2} \\ \\ = \frac{1}{10^2} \\ \\ = \frac{1}{100}$
