The order and degree of the differential equation $\left(\frac{d^2y}{dx^2}\right)^{2/3} = \left(x + \frac{dy}{dx}\right)^{1/2}$ are:
Step-by-Step Solution
Key Concept: Before reading off the order and degree, raise both sides to a suitable power so that every derivative appears with an integer exponent and the equation becomes a polynomial in the derivatives.
