Explications étape par étape
Bonjour
Écrire le plus simplement possible :
H = (-2)^5 - 3^4
H = -32 - 81
H = (-113)
I = (64 x 10^3)/(5 x 10^(-2))
I = (64/5) x 10^(3+2)
I = 12,8 x 10^5
I = 1 280 000
J = ((-3)^5 x 5^4) / (15^2 x 3^4)
J = ((-3)^5 x 5^4) / (3^2 x 5^2 x 3^4)
J = (-3)^5 x 5^(4-2) x 3^(-2-4)
J = (-3)^5 x 5^2 x 3^(-6)
J = -3^5 x 5^2 x 3^(-6)
J = -(3^(5-6)) x 25
J = -3^(-1) x 25
J = -25/3
K = (4,5 x 10^(-4) x 8 x 10^6) / (3^2 x 10^2)
K = (3^2 x 2^3)/(2 x 3^2) x 10^(-4+6-2)
K = (2^(3-1)) x 10^0
K = 2^2
K = 4
L = (7 x 10^4) / (2 x (10^3)^2)
L = (7/2) x 10^(4-3*2)
L = 3,5 x 10^(4-6)
L = 3,5 x 10^(-2)
L = 0,035
M = (54 x 10^(-1) - 83 x 10^(-2)) / 10^(-2)
M = 54 x 10^(-1+2) - 83 x 10^(-2+2)
M = 54 x 10 - 83 x 10^0
M = 540 - 83
M = 457
