Detail solution
  1. Let u=2xu = 2 x.

  2. ddu3u=3ulog(3)\frac{d}{d u} 3^{u} = 3^{u} \log{\left(3 \right)}

  3. Then, apply the chain rule. Multiply by ddx2x\frac{d}{d x} 2 x:

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

      1. Apply the power rule: xx goes to 11

      So, the result is: 22

    The result of the chain rule is:

    232xlog(3)2 \cdot 3^{2 x} \log{\left(3 \right)}

  4. Now simplify:

    29xlog(3)2 \cdot 9^{x} \log{\left(3 \right)}


The answer is:

29xlog(3)2 \cdot 9^{x} \log{\left(3 \right)}
