Evaluate the following expressions if:
a = 1 x = -3
b = 2 y = -2
c = 3 z = -1

1. abc 9. 4(5z - 3b) + x(c - 2a)

2. -4x + 7y 10. 5a - 2b I 5z - 2y

3. 3xyz 11. 7a + bx I cz

4 8b ^2 - 7b + 10 12. 4a^2 + 5y^2

5. (15xyz)^2 13. (5az)^3

6. {2c I 3y}^2 14. bc^2

7. 6y - (3a + 2z) 15. 11a^2 - 4b^2

8. 12x2 + 3xy - 5y2

Answer:

1. (1)(2)(3)

2. -4(-3) + 7(-2)

3. 3(-3)(-2)(-1)

4.8(-2) ^2 - 7(-2) + 10

5.(15(-3)(-2)(-1))^2

6. {2(3) I 3(-2)} ^2

7. 6(-2) - (3(1) +2(3)

8. 12x12 + 3(-3)(-2) - 5(-2)2

9. 4(5(-1) - 3(2) + (-3) (3-2(1)

10.5(1)-2(2) I 5(3) - 2(-2)

11.7(1) + (2)(-3) I (3)(-1)

12.4(1)^2+ 5(-2)^2

13.(5(1)(-1))^3

14. (2)(3)^2

15.11(1)^2 - 4(2)^2
