bonjour
A = 35 x 10 ⁻ ⁷
= 3.5 x 10 ⁻⁶
B = 0.047 + 0.097
B = 0.144
B = 1.44 x 10 ⁻¹
C = 21 x 10 ⁻⁹ : 6 x 10 ⁻⁴
C = 3.5 x 10 ⁻⁵
D = 80 x 10 ⁴ : 10 ⁻¹⁶
D = 80 x 10 ²⁰
= 8 x 10 ²¹
Réponse :
A=35*10^-60+53
A=35*10^-7
A=3,5*10*10^-7
A=3,5*10^-6
B=0,047+0,097
B=0,144
B=1,44*10^-1
C=(7*3)/6*10^-9*10^4
C=21/6*10^-5
C=3,5*10^-5
D=(80*10^4)/10^-12*10^-4
D=80*10^4*10^12*10^4
D=80*10^20
D=8*10*10^20
D=8*10^21
