(0,001)^3-x = 10^5
(1/1000)^3-x = 10^5
(1/10^3)^3-x = 10^5
(10^-3)^3-x = 10^5
10^-3(3-x) = 10^5
10^-9+3x = 10^5 (sisakan pangkat saja)
-9+3x = 5
3x=5+9
3x=14
x= 14/3 =4 2/3

[tex](0,001) ^{3-x} =10^5\\ (10 ^{-3}) ^{3-x} =10^5\\ 10^{-3(3-x)} =10^5\\ 10^{-9+3x} =10^5\\ \\ -9 +3x = 5\\ 3x = 5 + 9\\ 3x = 14\\ x = \frac{14}{3}\\ \bold{x=4 \frac{2}{3} = 4,667} [/tex]
