Derivative of y=(2x+3)^5

1. Let $u = 2 x + 3$.

2. Apply the power rule: $u^{5}$ goes to $5 u^{4}$

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

   1. Differentiate $2 x + 3$ term by term:

      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: $2$

      2. The derivative of the constant $3$ is zero.

      The result is: $2$

   The result of the chain rule is:

   $$10 \left(2 x + 3\right)^{4}$$

4. Now simplify:

   $$10 \left(2 x + 3\right)^{4}$$

The answer is:

$$10 \left(2 x + 3\right)^{4}$$
