What is the primary purpose of using the product rule in calculus?

• To differentiate a product of functions

• To integrate a product of functions

• To find the limit of a function

• To differentiate a sum of functions

How can the square root of a number be expressed in terms of exponents?

• As a power of 2

• As a power of 1

• As a power of 1/2
