The video tutorial explains how to simplify an expression with exponents and convert it to radical form. It starts by introducing the problem of simplifying x raised to the 3/4 power, then raised to the 2/11 power. The tutorial applies the exponent multiplication rule, simplifies the expression to x raised to the 3/22 power, and demonstrates how to input this into a computer. Finally, it explains how to convert the simplified expression into radical form, highlighting the roles of the numerator and denominator in determining the exponent and index of the radical.
