Order and degree of the differential equation
$\frac{d^2 y}{d x^2}=\left\{y+\left(\frac{d y}{d x}\right)^2\right\}^{1 / 4}$are
Answer & explanation
Correct answer: option 4
The given differential equation can be written as
$\left(\frac{d^2 y}{d x^2}\right)^4=\left\{y+\left(\frac{d y}{d x}\right)^2\right\}$
Clearly, its order and degree are 2 and 4 respectively.
