The sum of the order and degree of the differential equation x ( d^2 y d x^2 )^ 1 2 = (1+ d y d x )^ 4 3 is
Options
- A5
- B8
- C12
- D10
Correct answer
A. 5
Step-by-step solution
x ( d^2 y d x^2 )^ 1 / 2 = (1+ d y d x )^ 4 / 3 Squaring both sides x^2 ( d^2 y d x^2 )= (1+ d y d x )^ 8 / 3 Cubing both sides x^6 ( d^2 y d x^2 )^3= (1+ d y d x )^8 So, degree =3 , order =2 Sum =3+2=5 .
