Math Problem Statement

given y=3 power xsquared find dy/dx

Solution

Given the function y=3x2y = 3^{x^2}, we want to find the derivative dydx\frac{dy}{dx}.

Steps:

  1. Recognize that this is an exponential function where the exponent itself is a function of xx.

  2. Use the chain rule and logarithmic differentiation. For a function of the form y=au(x)y = a^{u(x)}, the derivative is: dydx=au(x)ln(a)dudx\frac{dy}{dx} = a^{u(x)} \cdot \ln(a) \cdot \frac{du}{dx} Here, a=3a = 3 and u(x)=x2u(x) = x^2.

  3. Differentiate y=3x2y = 3^{x^2} using the formula above: dydx=3x2ln(3)ddx(x2)\frac{dy}{dx} = 3^{x^2} \cdot \ln(3) \cdot \frac{d}{dx}(x^2)

  4. The derivative of x2x^2 is 2x2x, so: dydx=3x2ln(3)2x\frac{dy}{dx} = 3^{x^2} \cdot \ln(3) \cdot 2x

Thus, the derivative is: dydx=2x3x2ln(3)\frac{dy}{dx} = 2x \cdot 3^{x^2} \cdot \ln(3)

Tip: When differentiating exponential functions, the logarithmic base of the exponent is crucial in getting the right factor for the derivative.
