Example, 2 Express the following in the form of a + ib: (-5i) (1/8 π) (-5i) (1/8 π) = β 5 Γ 1/8 Γ i Γ i = (β5)/8 Γ i 2 = (β5)/8 Γ (β(β1) )2 = (β5)/8 Γ (β1) = 5/8 = 5/8 + 0 = 5/8 + i0 Example 2 Express the following in the form of a + bi (ii) (βπ) (2π) (β1/8 π)^3 (βπ) (2π) (β1/8 π)^3 = (βπ)(2π) (β1/8)^3 π^3 = β1 Γ 2 Γ(β1/(8 Γ 8 Γ 8)) Γ (π Γ π Γ π3) = 2 Γ 1/(8 Γ 8 Γ 8) Γ (π^(3+1+1) ) = 1 Γ 1/(4 Γ 8 Γ 8) Γ (π5) = 1/256 Γ (π4)π = 1/256 (π2)2 π = 1/256 (β1)^2 π = 1/256 (1)π = 1/256 π = 0 + 1/256 π
