$y = 5 e^{x} + 3$

Step 1

By the Sum Rule, the derivative of $5 e^{x} + 3$ with respect to $x$ is $\frac{d}{d x} [5 e^{x}] + \frac{d}{d x} [3]$ .

$\frac{d}{d x} [5 e^{x}] + \frac{d}{d x} [3]$

Step 2

Evaluate $\frac{d}{d x} [5 e^{x}]$ .

Step 2.1

Since $5$ is constant with respect to $x$ , the derivative of $5 e^{x}$ with respect to $x$ is $5 \frac{d}{d x} [e^{x}]$ .

$5 \frac{d}{d x} [e^{x}] + \frac{d}{d x} [3]$

Step 2.2

Differentiate using the Exponential Rule which states that $\frac{d}{d x} [a^{x}]$ is $a^{x} \ln (a)$ where $a$ = $e$ .

$5 e^{x} + \frac{d}{d x} [3]$

Step 3

Differentiate using the Constant Rule.

Step 3.1

Since $3$ is constant with respect to $x$ , the derivative of $3$ with respect to $x$ is $0$ .

$5 e^{x} + 0$

Step 3.2

Add $5 e^{x}$ and $0$ .

$5 e^{x}$
