This problem requires you to do arithmetic using complex numbers. It’s very much like ordinary algebra, except that you must remember that , and also to put your final. answer into the standard (“rectangular”) form .
Also remember, since is a radical (it’s ), we divide by rationalizing the denominator, which means we have to multiply top and bottom by the conjugate of the denominator. It is helpful to remember that .
