  1. Identify Product Rule: To find the derivative of yy with respect to xx, we need to use the product rule because yy is a product of two functions, x\sqrt{x} and exe^{x}.
  2. Define Functions: Let u=xu = \sqrt{x} and v=exv = e^{x}. Then, we need to find the derivatives of uu and vv with respect to xx.
  3. Find Derivatives: The derivative of uu with respect to xx is (1/2)x(1/2)(1/2)x^{(-1/2)} because the derivative of x(1/2)x^{(1/2)} is (1/2)x(1/21)(1/2)x^{(1/2 - 1)}.
  4. Apply Product Rule: The derivative of vv with respect to xx is exe^{x} because the derivative of exe^{x} with respect to xx is exe^{x}.
  5. Substitute into Formula: Now, apply the product rule: (dydx)=u(x)v(x)+u(x)v(x)(\frac{dy}{dx}) = u'(x)v(x) + u(x)v'(x).
  6. Simplify Expression: Substitute the derivatives and functions into the product rule: (dydx)=(12)x(12)ex+xex(\frac{dy}{dx}) = (\frac{1}{2})x^{(-\frac{1}{2})}e^{x} + \sqrt{x}e^{x}.
  7. Combine Terms: Simplify the expression: (dydx)=(12)x(12)e(x)+x(12)e(x).(\frac{dy}{dx}) = (\frac{1}{2})x^{(-\frac{1}{2})}e^{(x)} + x^{(\frac{1}{2})}e^{(x)}.
  8. Final Answer: Combine the terms: dydx=ex(12x12+x12)\frac{dy}{dx} = e^{x}\left(\frac{1}{2}x^{-\frac{1}{2}} + x^{\frac{1}{2}}\right).
  9. Final Answer: Combine the terms: (dy)/(dx)=ex((1/2)x(1/2)+x(1/2))(dy)/(dx) = e^{x}((1/2)x^{(-1/2)} + x^{(1/2)}).The final answer is (dy)/(dx)=ex((1/2)x(1/2)+x(1/2))(dy)/(dx) = e^{x}((1/2)x^{(-1/2)} + x^{(1/2)}).
