Tutorial - Finding the absolute value of a complex number ex 4, (-8i)

The video tutorial explains how to identify and work with complex numbers, focusing on imaginary numbers where the real part (A) is zero. It demonstrates how to determine the values of A and B in a complex number and calculates the absolute value of an imaginary number, using the example of -8i. The process involves squaring the imaginary part and taking the square root to find the absolute value.

What is the result of 0 squared plus (-8) squared?

What is the absolute value of the complex number -8i?
