Transcript text: Find $G^{\prime}(w)$ if $G(w)=\frac{7}{9 w^{6}}+7 \sqrt{w}$.
Solution
Solution Steps
Step 1: Define the Function
We start with the function \( G(w) \) given by:
\[
G(w) = \frac{7}{9 w^{6}} + 7 \sqrt{w}
\]
Step 2: Differentiate the Function
To find the derivative \( G^{\prime}(w) \), we apply the power rule to each term in the function. The derivative of \( \frac{7}{9 w^{6}} \) is calculated as follows:
\[
\frac{d}{dw}\left(\frac{7}{9 w^{6}}\right) = -\frac{14}{3 w^{7}}
\]
The derivative of \( 7 \sqrt{w} \) is:
\[
\frac{d}{dw}(7 \sqrt{w}) = 7 \cdot \frac{1}{2\sqrt{w}} = \frac{7}{2\sqrt{w}}
\]
Step 3: Combine the Results
Combining the derivatives from both terms, we have:
\[
G^{\prime}(w) = -\frac{14}{3 w^{7}} + \frac{7}{2\sqrt{w}}
\]
Final Answer
Thus, the derivative \( G^{\prime}(w) \) is:
\[
\boxed{G^{\prime}(w) = -\frac{14}{3 w^{7}} + \frac{7}{2\sqrt{w}}}
\]
