Simplify i^3*9

Problem

i3⋅9

Solution

1. Identify the power of the imaginary unit i

2. Apply the property of imaginary numbers where i2=−1

3. Rewrite i3 as the product of i2 and i

i3=i2⋅i

4. Substitute −1 for i2 to simplify the power.

i3=−1⋅i

i3=−i

5. Multiply the simplified imaginary part by the constant 9

−i⋅9=−9*i

Final Answer

i3⋅9=−9*i
