Question

determine o valor de x na equação exponencial 10x3=1/100

Answer 1

$10x^3=\frac{1}{100} \\ \\ 10x^3=10^{-2} \\ \\ x^3=\frac{10^{-2}}{10} \\ \\ x^3=10^{-3} \\ \\ x^3=(\frac{1}{10})^3 \\ \\ \boxed{x=\frac{1}{10}}$

Answer 2

10x^3 = 1/ 100
10x^3 = 1 / 10^2
10x^3 = 10^-2
x^3 = 10^-2 * 1/10
x^3 = 10^-2 * 10^-1
x^3 = 10^-3
x^3 = (1/10)^3

x = 1/10
