Apply the power rule: goes to
Then, apply the chain rule. Multiply by :
Apply the power rule: goes to
The result of the chain rule is:
The derivative of a constant times a function is the constant times the derivative of the function.
The derivative of a constant times a function is the constant times the derivative of the function.
Apply the power rule: goes to
So, the result is:
So, the result is:
The derivative of the constant is zero.
The result is:
The answer is:
