Evaluate each expression and write your answer in a separate sheet of paper. Show your solution

1. Evaluate 5× - 6 if × = 2

2. Evaluate 3× + 4y - 5 if x = 2 and y = 4

3. If a = 4 and b = 5, evaluate 2ab - 3b

4.If m = 2 and n = 3, what is the result of m⁴ - n?

5. If a 2, b = 4 and c = 6, evaluate b+c/a + c²/ a+ b

Answer:

1. 5(2) - 6

5(2) = 10

10 - 6 = 4

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

3(2) = 6

4(4) = 16

6+16 = 22

22-5 = 17

3. 2(4)(5) - 3(5)

2(4) = 8

8(5) = 40

3(5) = 15

40-15 = 25

4. 2⁴-3

2⁴ = 16

16-3 = 13

5. 4+6/2+6²/2+4

6² = 36

6/2 = 3

36/2 = 18

4+3 = 7

7+18 = 25

25+4 = 29
