Find the sum of the order and degree of the differential equation y=x ( dy dx )^3+ d^2ydx^2

Question

Accepted Answer

Correct answer: B. (b) Since order and degree of the given differential equation y=x ( dy dx )^3+ d^2ydx^2 are 2 and 1 respectively. So, the sum =3

$Find the sum of the order and degree of the differential equation y = x (\frac{dy}{dx})^{3} + \frac{d ^{2} y}{d x ^{2}}$
