The notation ak means the matrix a multiplied with itself k times. find an example of non zero 2×2 matix whose square is zero matrix

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

1. 3.4/4

2. 0.8/7

3. 0.5 x 3

4. 0.9 x 6

5. 10.8

6. 2.35

7. 0.567

8. 9.35

9. 0.02

10. 0.06

11. 0.16

12. 0.42

13. 0.63

14. 5.6

15. 8.1

16. 9.9

17. 0.28

18. 0.48

19. 0.27

20. 0.49

21. 0.45

22. 0.72

23. 0.9

24. 0.88

25. 0.75

26. 0.16

27. 0.328

28. 0.495

29. 0.72

30. 1.068

the function makes a strait line horizontally with no x intercept but a y intercept at 9.

c. side angle side. u shares the same sides
