Soal : Dik : X 1 = 3, X 2 = 4, X 3 = 6 Y 1 = 4, Y 2 = 1, Y 3 = 5 Maka : 1. =X 1+X 2+X 3 = 3+4+6 = 13

2. = = 4 {X 2 + X 3} 4 { 4 + 6} 4 {10} 40 3. = n. k = 3. 8 = 24

8. 9. = n. k = 3. 7 = 21 = = 5 Xi + 5 X 2 + 5 X 3 5. 3 + 5. 4 + 5. 6 15 + 20 + 30 65

10. 11. = = = (X 1 + 2 X 1)+(X 2 + 2 X 2) (3 + 2. 3)+(4 + 2. 4) (3 + 6)+(4 + 8) 9 + 12 21 =Y 1+Y 2+Y 3 = 4+1+5 = 10

12. 13. = = 4 {y 2 + y 3} 4 { 1 + 5} 4 {6} 24 = n. k = 3. 8 = 24

18. = n. k = 3. 7 = 21 19. = = 5 Y 1 + 5 Y 2 + 5 Y 3 5. 4 + 5. 1 + 5. 5 20 + 5 + 25 50

20. = = = (Y 1 + 2 Y 1)+(Y 2 + 2 Y 2) (4 + 2. 4)+(1 + 2. 1) (4 + 8)+(1 + 2) 12 + 3 15
