Simplifying Variable Radicands in Industrial Design

In a facilities management blueprint, the area of a square ventilation grate is represented by the variable expression z30z^{30}. To determine the side length, a technician must simplify the square root of the area, z30\sqrt{z^{30}}. Based on the standard mathematical rule for finding the principal square root of a variable raised to an even power, what specific operation must be performed on the exponent 30, and what is the resulting simplified expression for the side length? (Assume z≥0z \ge 0).
