Tutorial - Finding the absolute value of a complex number ex 2, (10 - 7i)

The video tutorial explains how to find the absolute value of a complex number. It begins by introducing the formula for the absolute value of a complex number A + BI, which is sqrt(a^2 + b^2). The instructor identifies the components A and B, with A being 10 and B being -7. The tutorial then demonstrates the calculation of the absolute value, resulting in sqrt(149). Finally, it checks if the result can be simplified, concluding that it cannot be further simplified.

What is the result of adding the squared values of A and B?

Can the square root of the sum of the squared values be simplified? Explain your reasoning.
