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)
