Step 1: Recognize that the function g(x) = e^{x^2 \ln x} is a composite function. To differentiate it, we will use the chain rule. The chain rule states that if y = f(u) and u = g(x), then dy/dx = f'(u) * g'(x).
Step 2: Start by differentiating the outer function e^u, where u = x^2 \ln x. The derivative of e^u with respect to u is e^u. So, the derivative of g(x) with respect to x will include e^{x^2 \ln x}.
Step 3: Now, differentiate the inner function u = x^2 \ln x. This requires the product rule because u is a product of x^2 and \ln x. The product rule states that if u = v * w, then u' = v'w + vw'.
Step 4: Apply the product rule to u = x^2 \ln x. Here, v = x^2 and w = \ln x. The derivative of v = x^2 is v' = 2x, and the derivative of w = \ln x is w' = 1/x. Substituting into the product rule, we get u' = (2x)(\ln x) + (x^2)(1/x). Simplify this to u' = 2x \ln x + x.
Step 5: Combine the results from Step 2 and Step 4. The derivative of g(x) is g'(x) = e^{x^2 \ln x} * (2x \ln x + x). Factor out x from the second term to write the final expression as g'(x) = x e^{x^2 \ln x} (2 \ln x + 1).
