Simplify i^5*5

Problem

i5⋅5

Solution

1. Identify the properties of the imaginary unit i where i2=−1

2. Determine the value of i5 by using the cyclic nature of powers of i which repeat every four powers: i1=i i2=−1 i3=−i and i4=1

3. Rewrite the power as i5=i4⋅i

4. Substitute the known value i4=1 into the expression.

i5=1⋅i

i5=i

5. Multiply the result by the constant 5.

i⋅5=5*i

Final Answer

i5⋅5=5*i
