Step-by-step explanation:
Given in the question a complex fraction
<h3>Step1</h3>To divide complex numbers, you must multiply by the conjugate. To find the conjugate of a complex number all you have to do is change the sign between the two terms in the denominator.
Distribute (or FOIL) in both the numerator and denominator to remove the parenthesis.
Simplify the powers of i, specifically remember that i² = –1.
