a.

| 3 – 2x | < 4

-4 < 3 – 2x < 4

-4 – 3 < -2x < 4 – 3

-7 < -2x < 1

7 > 2x > -1

-1 < 2x < 7

-1/2 < x < 7/2

Hp = { x| -1/2 < x < 7/2 , x ∈  R }

b.

| x – 5| = 8

x – 5 = 8

x = 8 + 5

x = 13

atau

x – 5 = -8

x = -8 + 5

x = -3

Hp = { -3 , 13 }

3. (a² . b⁻³/ b⁻⁴) . a²

a²⁺² . b⁻³⁺⁴

a⁴ . b
