A = (43 x 10^3)/(-5 x 10^5)
A = (-43/5) x 10^(3-5)
A = -8,6 x 10^(-2)
B = (73 x 10^(-4))/(-25 x 10^(-6))
B = (-73/25) x 10^(-4+6)
B = -2,92 x 10^2
C = (12 x 10^(-3))/(-215 x 10^5)
C = -(12/215) x 10^(-3-5)
C = -12/215 x 10^(-8)
C ~ -5,58 x 10^(-2) x 10^(-8)
C ~ -5,58 x 10^(-2-8)
C ~ -5,58 x 10^(-10)
D = (18 x 10^7)/(11 x 10^(-7))
D = (18/11) x 10^(7+7)
D ~ 1,64 x 10^14
