Refresher:
Complex numbers can be expressed as a combination of real and imaginary numbers. The standard notation of a complex number is given by z = x + iy, where x is the real part of z and iy is the imaginary part of the complex number z. Also, “i” is called the “iota” and i = -1

Solve:

If z = 2 – 3i, then find z²
