30. Consider the equation (5x²y + 6x³y² + 4xy²) dx + (2x³ + 3x+y + 3x²y) dy = 0. (a) Show that the equation is not exact. (b) Multiply the equation by x"y" and determine values for n and m that make the resulting equation exact. (c) Use the solution of the resulting exact equation to solve the original equation.
