écris sous la forme d'une puissance de 10 1: 10² × 10⁶= 2: 10-⁷×10-³= 3: 10⁹×10¹¹= 4:10¹²×10-¹⁰= 5:10-⁸×10⁶= 6:10²/10⁷= 7:10⁴/10-3= 8:10-¹³/10¹⁰= 9:10-⁶×10⁹/10-

Réponse:

1) 10² × 10⁶ = 10²+⁶ = 10⁸

2) 10`⁷ × 10`³ = 10`⁷+`³ = 10`¹⁰

3) 10⁹ × 10¹¹ = 10⁹+¹¹ = 10²⁰

4) 10¹² × 10`¹⁰ = 10¹²+`¹⁰ = 10²

5) 10`⁸ × 10⁶ = 10`⁸+⁶ = 10`²

6) 10²/10⁷ = 10²-⁷ = 10`⁵

7) 10⁴/10`³ = 10⁴-`⁷ = 10¹¹

8) 10`¹³/10¹⁰ = 10`¹³-¹⁰ = `²³

9) 10`⁶×10⁹/10`⁵ = 10`⁶+⁹/10`⁵ = 10³/`⁵ = 10³-`⁵ = 10⁸
