Simplify i^3*4

Problem

i3⋅4

Solution

1. Identify the components of the expression, which consists of the imaginary unit i raised to the third power multiplied by the constant 4

2. Recall the powers of the imaginary unit i where i1=i and i2=−1

3. Evaluate i3 by breaking it down into i2⋅i

4. Substitute the value of i2 into the expression to find i3=−1⋅i=−i

5. Multiply the result by the constant 4 to reach the final simplified form.

Final Answer

i3⋅4=−4*i
