Quizplus · Accepted Answer

The square root of a square function, such as $\sqrt{(z - 7)^2}$, simplifies to the absolute value of the original expression inside the square, which is $|z - 7|$. This accounts for both the positive and negative roots that would square to give the original expression under the square root.
