The degree of differential equation $\frac{d^2 y}{d x^2}+3\left(\frac{d y}{d x}\right)^2=x \log \frac{d^2 y}{d x^2}$ is :
Answer & explanation
Correct answer: option 4
Since the equation is not a polynomial in all the differential coefficient so the degree of equation is not defined.
Hence (4) is the correct answer.
