Evaluate the integral using u substitution of a expression to the fourth power

The video tutorial explains the process of u-substitution in calculus, focusing on identifying 'u' and 'du', changing the bounds of integration, and performing the integration. The instructor guides through the steps of rewriting the integral, adjusting the bounds, and calculating the final result, emphasizing the importance of understanding each step in the process.

Explain the process of finding the integral from the new bounds.

What is the final value obtained after evaluating the integral?
