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 the square root of the sum of the squares of its real and imaginary parts. The instructor identifies the real part (A) and the imaginary part (B) of the given complex number, then demonstrates the calculation of the absolute value using these components. The tutorial concludes with the final result of the calculation, providing a clear understanding of the process.
