The solution

You have entered [src]
log(x) + 8*log(x)
$$\log{\left(x \right)} + 8 \log{\left(x \right)}$$
log(x) + 8*log(x)
Detail solution
  1. Differentiate term by term:

    1. The derivative of is .

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. The derivative of is .

      So, the result is:

    The result is:
