How to rationalize the radical to evaluate a limit

The video tutorial explains how to handle radicals in fractions by using conjugates. It highlights the importance of multiplying by the conjugate to eliminate radicals and discusses why direct substitution may not work in certain cases. The tutorial walks through the multiplication and simplification process, emphasizing the cancellation of middle terms. Finally, it demonstrates the evaluation of the expression as the variable approaches a specific value, ensuring a clear understanding of the mathematical concepts involved.
