Derivative of -2x*ln4

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. Apply the power rule: $x$ goes to $1$

      So, the result is: $-2$

   So, the result is: $- 2 \log{\left(4 \right)}$

2. Now simplify:

   $$- \log{\left(16 \right)}$$

The answer is:

$$- \log{\left(16 \right)}$$
