Math Problem Statement

d/dx(sqrt(e^x))

Solution

To differentiate ex\sqrt{e^x} with respect to xx, we will use the chain rule. The function can be rewritten as (ex)1/2(e^x)^{1/2}.

Let's go through the steps:

  1. Rewrite the function: ex=(ex)1/2\sqrt{e^x} = (e^x)^{1/2}

  2. Differentiate using the chain rule: The chain rule states that if you have a composite function f(g(x))f(g(x)), then ddxf(g(x))=f(g(x))g(x)\frac{d}{dx} f(g(x)) = f'(g(x)) \cdot g'(x).

    Let u=exu = e^x. Then ex=u1/2\sqrt{e^x} = u^{1/2}.

    • Differentiate u1/2u^{1/2} with respect to uu: dduu1/2=12u1/2\frac{d}{du} u^{1/2} = \frac{1}{2} u^{-1/2}

    • Differentiate exe^x with respect to xx: ddxex=ex\frac{d}{dx} e^x = e^x

  3. Apply the chain rule: ddxex=dduu1/2dudx=12u1/2ex\frac{d}{dx} \sqrt{e^x} = \frac{d}{du} u^{1/2} \cdot \frac{du}{dx} = \frac{1}{2} u^{-1/2} \cdot e^x

  4. Substitute back u=exu = e^x: 12(ex)1/2ex=12exex=12ex\frac{1}{2} (e^x)^{-1/2} \cdot e^x = \frac{1}{2} \cdot \frac{e^x}{\sqrt{e^x}} = \frac{1}{2} \cdot \sqrt{e^x}

Therefore, the derivative of ex\sqrt{e^x} with respect to xx is: ddxex=12ex\frac{d}{dx} \sqrt{e^x} = \frac{1}{2} \sqrt{e^x}
