Final answer:
The equation 3x²y is not exact and cannot be solved.
Step-by-step explanation:
The equation 3x²y is not an exact equation. In order for an equation to be exact, the partial derivatives with respect to x and y must be equal. Let's differentiate the equation with respect to x and y:
∂/∂x (3x²y) = 6xy
∂/∂y (3x²y) = 3x²
Since the partial derivatives are not equal, the equation is not exact and cannot be solved.
