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.
