The ORDER and DEGREE of the DE (d²y/dx²)³ + (dy/dx)⁵ + y = 0 are:
AOrder 3, degree 2
BOrder 2, degree 3
COrder 5, degree 1
DOrder 2, degree 5
Answer & Solution
Correct answer: B. Order 2, degree 3
Order = highest derivative present = d²y/dx² → 2. Degree = power of highest-order derivative = (d²y/dx²)³ → 3.
