The video tutorial explains how to handle imaginary numbers, specifically focusing on rationalizing the denominator when dividing by imaginary numbers. It covers the concept of imaginary numbers, represented by 'i', and their distinction from real numbers. The tutorial demonstrates the process of rationalizing the denominator by multiplying the numerator and denominator by 'i', simplifying the expression, and converting it into complex form. The goal is to avoid division by imaginary numbers and express results in a preferred complex number format.
