Derivative of y=4log2(x)+8x

The solution

You have entered [src]

  log(x)      
4*------ + 8*x
  log(2)

$$8 x + 4 \frac{\log{\left(x \right)}}{\log{\left(2 \right)}}$$

4*(log(x)/log(2)) + 8*x

Detail solution

Differentiate $8 x + 4 \frac{\log{\left(x \right)}}{\log{\left(2 \right)}}$ term by term:
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. The derivative of a constant times a function is the constant times the derivative of the function.
    1. The derivative of $\log{\left(x \right)}$ is $\frac{1}{x}$ .
    So, the result is: $\frac{1}{x \log{\left(2 \right)}}$
  So, the result is: $\frac{4}{x \log{\left(2 \right)}}$
2. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $8$
The result is: $8 + \frac{4}{x \log{\left(2 \right)}}$

The answer is:

$8 + \frac{4}{x \log{\left(2 \right)}}$
