Rationalizing Factors in Circuit Load Calculations

An apprentice technician at an electronics manufacturing company is documenting a circuit load formula that includes the expression 28x4\frac{2}{\sqrt[4]{8x}}. To standardize the formula for the team's software, the technician must rationalize the denominator. After rewriting the expression as 223x4\frac{2}{\sqrt[4]{2^3x}}, the reference manual states they must multiply both the numerator and denominator by the rationalizing factor 2x34\sqrt[4]{2x^3}. Recall and explain the specific mathematical reason why 2x34\sqrt[4]{2x^3} is chosen as the rationalizing factor.
