Jawab Ya teman teman

1. FPB 72 dan 96 = 24
2. KPK 36 dan 45 = 180
3. n= - 41
4. n = 90

12. Fpb 72 dan 96
72 = 2x2x2x3x3 = 2³ x 3²
96 = 2x2x2x2x2x3 = 2^5 x 3
Fpb = 2³ x 3 = 24

13. KPK 36 dan 45
36 = 2x2x3x3 = 2² x 3²
45 = 3x3x5 = 3² x 5
Kpk = 2²x3²x5 = 180

14. 48 + (-89)
= 48 - 89
= -41

15. 56 - (-34)
= 56 + 34
= 90

Semoga membantu :)
