= 6x10^2 / 25x10^4 = 0,0024 = 2,4x10^-3

Bonsoir,

C = (1,5x10^7x4x10^-5)/(25x10^4)

C = (1,5x10000000x4x0,00001)/(25x10000)

C = (15000000x4x0,00001)/(25x10000)

C = (60000000x0,00001)/(25x10000)

C = 600/(25x10000)

C = 600/250000

C = 0,0024

C = 2,4x10^-3

L'écriture décimale de C est 0,0024.

L'écriture scientifique de C est 2,4x10^-3.
