How to find the antiderivative using a negative exponent

The video tutorial covers the concept of antiderivatives, focusing on using the power rule to simplify expressions. The instructor explains the importance of rewriting expressions to avoid fractions and demonstrates the process of simplifying expressions by adding constants. The tutorial emphasizes the process of 'add and divide' instead of 'multiply and subtract' and prepares students for more complex topics.

What is the significance of adding the constant C at the end of the antiderivative?

Describe the difference between the processes of 'add and divide' and 'multiply and subtract' in the context of the power rule.
