Question

Evaluate complex variables. Write your answer(s) in the form a + bi. (a) i²−i

Answer 1

The expression i² - i evaluates to -1 - i, where i is the imaginary unit.

Step-by-step explanation:

When evaluating the expression i² - i, we use the fact that i is the square root of -1. Hence, i² is equal to -1. The expression simplifies as follows:

i² - i = (-1) - i = -1 - i

This is a complex number in the form a + bi where a is the real part and b is the imaginary part. In our case, a = -1 and b = -1, making the final answer -1 - i.
