C= (5 x 10^-3 x 12 x 10^6) / 15 x 10^2 x 8 x 10^-5

C= (5 x 12) / (15 x 8) x (10^-3 x 10^6) / (10^2 x 10^-5)

C= 60/120 x 10^3/10^-3

C= 0,5 x 10^6

C= 5 x 10^5

C= 500000

C= 5x 10^-3 x 12 x 10^6 / 15 x 10^2 x 8 x 10^-5
C = ( 5 * 12 * 10^-3 * 10^6) /(15 * 8 * 10^2 * 10^-5)

C = 3 * 10^( - 3+6) / 3 * 2 * 10^(2 - 5)

C = 10^3 /2 * 10^-3

C = 10^3 * 10^3 * 1/2

C = 1/2 * 10^6
