Question

Write the degree of the differential equation x \[\left( \frac{d^2 y}{d x^2} \right)^3 + y \left( \frac{dy}{dx} \right)^4 + x^3 = 0\]

Solution

\[\left( \frac{d^2 y}{d x^2} \right)^3 + y \left( \frac{dy}{dx} \right)^4 + x^3 = 0\] 
The highest order derivative is \[\frac{d^2 y}{d x^2}\]  and its power is 3.
Therefore, the degree of given differential equation is 3.
