Question

qual e o calculo ? p . s : resposta 0,0001

Answer 1

 
 10^-3 =  . 10^-310^-1 ==> 10^-4 ==> 0,0001
   10

Answer 2

Razão entre potências de mesma base: Conservamos a base e subtraímos os expoentes

$10^{-3}\div10=\dfrac{10^{-3}}{10}\\\\\\10^{-3}\div10=\dfrac{10^{-3}}{10^{1}}\\\\\\10^{-3}\div10=10^{-3-1}\\\\\\10^{-3}\div10=10^{-4}\\\\\\10^{-3}\div10=(\dfrac{10}{1})^{-4}$

Invertendo a fração e trocando o sinal do expoente:

$10^{-3}\div10=(\dfrac{1}{10})^{4}\\\\\\10^{-3}\div10=\dfrac{1^{4}}{10^{4}}\\\\\\10^{-3}\div10=\dfrac{1}{10000}\\\\\\\boxed{\boxed{10^{-3}\div10=0,0001}}$
