  1. 1. The problem
    Finding a derivative
    ddx[e2x]\frac{d}{dx}\left[{e}^{2x}\right]
  2. 2. Step by step
    1. ddx[e2x]=2e2x\frac{d}{dx}\left[{e}^{2x}\right] = 2{e}^{2x}
      Exponential rule: d/dx[eᵘ] = eᵘ·u′
    2. ddx[2x]=2\frac{d}{dx}\left[2x\right] = 2
      Constant multiple rule
    3. f′(x)=2e2xf'(x) = 2{e}^{2x}
      Combine and simplify
  3. 3. The answer
    f′(x)=2e2xf'(x) = 2{e}^{2x}

    f'(x) = 2e^(2x)

Transcript

The problem. Here is the problem: d by d x e to the power 2x. Find the derivative of e to the power 2x with respect to x.

Step by step. Exponential rule: d by d x[eᵘ] equals eᵘ times u prime. Constant multiple rule. Combine and simplify.

The answer. So the answer is f prime of x equals 2e to the power 2x. The derivative is built from the outside in: sums split into terms, constants factor out, products and quotients use their rules, and every composite function multiplies by the derivative of its inside (chain rule).

Check. Cross-checked numerically against an independent symbolic differentiator at 8 sample points, which checks out.
