Bonjour,
Exercice 4 :
Écrire le plus simplement possible :
H = (-2)^5 x (-3)^5
H = [(-2) x (-3)]^5
H = 6^5
H = 7776
I = (21 x 10^3)/(7 x 10^2)
I = (3 x 7)/7 x 10^(3-2)
I = 3 x 10
I = 30
J = ((-3)^5 x 5^4)/(15^2 x 3^4)
J = -3^(5-4) x 5^4 / (3 x 5)^2
J = -3 x 5^4 / (3^2 x 5^2)
J = -3^(1-2) x 5^(4-2)
J = -3^(-1) x 5^2
J = -25/3
K = (4,5 x 10^(-4) x 8 x 10^6)/(3^2 x 10^2)
K = (4,5 x 8 / 9) x 10^(-4+6-2)
K = (4,5 x 8)/(4,5 x 2) x 10^0
K = 8/2
K = (2 x 4)/2
K = 4
L = (7 x 10^4)/(2 x (10^3)^2)
L = 7/2 x 10^(4-3x2)
L = 3,5 x 10^(4-6)
L = 3,5 x 10^(-2)
L = 3,5/100
L = 0,035
M = ((10^2)^3)^2/(10^2 x 10^(-2))
M = 10^(2x3x2-2+2)
M = 10^12
M = 1 000 000 000 000
