9. Diapositive 1
( -8 )
2
= -8 × (-8) = 64

10. Diapositive 1
( -8 )
2
= -8 × (-8) = 64

11. Diapositive 1
( -8 )
2
= -8 × (-8) = 64

12. Diapositive 2
2
-3 = -3 × 3 = -9

13. Diapositive 2
2
-3 = -3 × 3 = -9

14. Diapositive 2
2
-3 = -3 × 3 = -9

15. Diapositive 3
Par quel nombre faut-il
multiplier -9 pour obtenir 81?
Par -9 car
9 × ( -4) = -36

16. Diapositive 3
Par quel nombre faut-il
multiplier -9 pour obtenir 81?
Par -9 car
9 × ( -4) = -36

17. Diapositive 3
Par quel nombre faut-il
multiplier -9 pour obtenir 81?
Par -9 car
-9 × ( -9) = 81

18. Diapositive 4
( -10 )
3
= -10 × (-10) × (-10) = -1000

19. Diapositive 4
( -10 )
3
= -10 × (-10) × (-10) = -1000

20. Diapositive 4
( -10 )
3
= -10 × (-10) × (-10) = -1000

21. Diapositive 5
( -1)
4
= -1 × (-1) × (-1) × (-1) = 1

22. Diapositive 5
( -1)
4
= -1 × (-1) × (-1) × (-1) = 1

23. Diapositive 5
( -1)
4
= -1 × (-1) × (-1) × (-1) = 1
