How do you differentiate #f(x)=(1+x^4)^(2/3)#?
1 Answer
f'(x)=
Explanation:
When dealing with the chain rule, it's sometimes best to treat our composition of functions as "layered," where each layer must be differentiated individually and all differentiated layers must finally be multiplied. Here, our outermost layer would be the polynomial raised to the
Differentiating the outer layer with the power rule, where the inner layer
Differentiating the inner layer with the power rule, we would get:
Multiply our differentiated layers together and simplify:
f'(x)=
f'(x)=
