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
