Question

Função exponencial: 10^3x=1/10000

Answer 1

$\displaystyle \mathsf{10^{3x} = \frac{1}{10000}}\\ \\ \displaystyle \mathsf{10^{3x} = 10000^{-1}}\\ \displaystyle \mathsf{10^{3x} = (10^4)^{-1}}\\ \displaystyle \mathsf{10^{3x} = 10^{-4}}\\ \displaystyle \mathsf{3x = -4}\\ \displaystyle \mathsf{x = \frac{-4}{3}}$

Resposta: $\displaystyle \mathsf{\frac{-4}{3}}$
