Simplifying Expressions and Radicals

The video tutorial explains how to simplify a mathematical expression involving radicals. It begins by addressing the problem statement and then proceeds to simplify the numerator by multiplying coefficients and radicands. The tutorial continues by simplifying the cube root in the denominator and concludes with rationalizing the denominator to eliminate the radical, resulting in a simplified expression.

What is the initial expression that needs to be simplified?
