Bonjour, pouvez-vous m’aider en maths puissance de 10 svp :

Explications étape par étape

Bonsoir

B = 10 x (10^(-7))^3 x 10^9

B = 10 x 10^(-7*3) x 10^9

B = 10^(1-21+9)

B = 10^(-11)

C = 2^3 x 5^3 x 10^8

C = (2 x 5)^3 x 10^8

C = 10^3 x 10^8

C = 10^(3+8)

C = 10^11

D = (10^(-2) x 10^(-7))/(10^6)

D = 10^(-2-7-6)

D = 10^(-15)

E = (10^(-4) x 10^9)/(10^5 x 10^(-7))

E = 10^(-4+9-5+7)

E = 10^7

F = ((10^4)^(-2) x 10)/(10^(-3))

F = 10^(4*(-2)+1+3)

F = 10^(-8+4)

F = 10^(-4)

G = [(10^13 x 10^(-9))/(10^(-14) x 10^(-8))]^2

G = (10^(13-9+14+8))^2

G = (10^26)^2

G = 10^(26*2)

G = 10^52

H = (20^6 x 10^(-9))/(2^6)

H = (2^6 x 10^6 x 10^(-9))/(2^6)

H = 10^(6-9)

H = 10^(-3)
