      Dividing square roots of imaginary numbers. This follows a similar process. Examples: Examples: Complex Numbers. Complex numbers are of the form a + bi, where a and b are real numbers. The number a is called the real part and b is called the imaginary part. If a is 0 they are called pure imaginary numbers. Add and subtract complex numbers
