Derivative of (1+2x)^30

1. Let $u = 2 x + 1$.

2. Apply the power rule: $u^{30}$ goes to $30 u^{29}$

3. Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(2 x + 1\right)$:

   1. Differentiate $2 x + 1$ term by term:

      1. The derivative of the constant $1$ is zero.

      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: $2$

      The result is: $2$

   The result of the chain rule is:

   $$60 \left(2 x + 1\right)^{29}$$

The answer is:

$$60 \left(2 x + 1\right)^{29}$$
