Solution: Chain Rule #3
Find the derivative of:
[latex]\Large{h(x) = \sqrt{e^{2x}}}[/latex]
Step 1:
We notice that the given function is a composite function, or a function within another function. To find the derivative of composite functions, we will use the chain rule. First, we can rewrite the function as:
[latex]\large{h(x) = (e^{2x})^{\frac{1}{2}}}[/latex]
We can see that the inner function is [latex]e^{2x}[/latex] and the outer function is the square root function or, the power of [latex]\frac{1}{2}[/latex].
The chain rule states:
[latex]\Large{\frac{d}{dx}f(g(x)) = f'(g(x)) \cdot g'(x)}[/latex]
Step 2:
Applying the chain rule, we have:
[latex]\Large{\frac{d}{dx}(e^{2x})^{\frac{1}{2}} = \frac{1}{2}(e^{2x})^{-\frac{1}{2}} \cdot \frac{d}{dx}(e^{2x})}[/latex]
To find [latex]\frac{d}{dx}e^{2x}[/latex], we can use the chain rule, as follows:
[latex]\large{\frac{d}{dx}e^{2x} = e^{2x} \cdot \frac{d}{dx}2x = 2e^{2x}}[/latex]
Combining everything, we have:
[latex]\large{\frac{d}{dx}(e^{2x})^{\frac{1}{2}} = \frac{2e^{2x}}{2\sqrt{e^{2x}}} = \frac{e^{2x}}{\sqrt{e^{2x}}}}[/latex]
Step 3:
Simplifying, we have:
[latex]\Large{ = e^{2x}(e^{2x})^{-\frac{1}{2}}}[/latex]
[latex]\Large{ = e^{2x}(e^{-x}) = e^x}[/latex]
Thus, this is the final answer for the derivative. So:
[latex]\Large{h'(x) = e^x}[/latex]
