Algebra 2 Learn how to simplify an expression by rationalizing denominator with complex numbers -7/i

The video tutorial covers basic arithmetic operations, focusing on division. It introduces the concept of imaginary numbers, particularly the imaginary unit 'i', and explains how to handle division involving imaginary numbers. The tutorial demonstrates the process of simplifying expressions with imaginary numbers in the denominator by multiplying the numerator and denominator by 'i'. The final result is a simplified expression without 'i' in the denominator.

Why is it important to avoid dividing by the imaginary unit I?

What is the final answer when dividing 7 by the imaginary unit I?
