Answer
The derivative of \( g(w) \) is \( g'(w) = 3e^{w} \).
Solution
We are given the function
\[
g(w)=\frac{3 e^{2w}+4e^{w}}{e^{w}}
\]
**Step 1: Simplify the function**
Divide each term in the numerator by \( e^{w} \):
\[
g(w)=\frac{3 e^{2w}}{e^{w}}+\frac{4 e^{w}}{e^{w}}=3e^{w}+4
\]
**Step 2: Differentiate the simplified function**
Differentiate \( g(w)=3e^{w}+4 \) with respect to \( w \):
\[
g'(w)=\frac{d}{dw}\left(3e^{w}+4\right)
\]
Since \(\frac{d}{dw}(e^{w})=e^{w}\) and the derivative of a constant is 0:
\[
g'(w)=3e^{w}+0=3e^{w}
\]
Thus, the derivative is
\[
g'(w)=3e^{w}
\]

Bonus Knowledge
To simplify \( g(w) \), we divide each term in the numerator by \( e^{w} \): \[ g(w) = \frac{3 e^{2 w}}{e^{w}} + \frac{4 e^{w}}{e^{w}} = 3 e^{w} + 4 \] Now, we can differentiate: \[ g'(w) = \frac{d}{dw}(3 e^{w} + 4) = 3 e^{w} \] So the derivative is: \[ g'(w) = 3 e^{w} \]
