Bonjour
10⁴ x 10 ³ = 10 ⁷ (les puissances s'ajoutent)
10² x 10⁻⁷ = 10 ⁻⁵
10⁸ x 10 ⁻²° = 10 ⁻¹²
10⁸ x 10 ⁻⁴ = 10⁴
a) (10⁹)⁴ = 10 ³⁶ (les puissances se multiplient)
b) 10⁻⁴ = 0,0001
c) 10⁹ = 1000 000 000
d) 10¹² x 10⁻⁸ x 10⁵ = 10 ⁹
e) 10⁶ = 1000000
e) 10⁴¹ x 10⁷ = 10 ⁴⁸
f) 10⁻³⁹ = 1 x 10⁻³⁹
g) 10⁷ = 0,0000001
h) 10⁸ = 100000000
h) (10⁻³)⁻⁶ = 10 ¹⁸
i) 10¹° = 10000000000
j) 10⁻⁵ = 0,00001
i)10²¹ = 1000000000000000000000
10⁻⁴ x 10 ⁻¹⁸ = 10⁻²²
