Tutorial - Simplifying an expression by rewriting it with the imaginary unit i ex 10, 3 + 2 root(-4)

The video tutorial demonstrates how to simplify an expression involving imaginary numbers. It begins by introducing the concept of imaginary numbers, specifically the square root of negative one, represented as 'i'. The instructor then rewrites the given expression using this concept and proceeds to simplify it step-by-step, ultimately expressing it in standard form. The tutorial concludes with the final simplified expression.
