The order and the degree of the differential equation [1+ ( d y d x )³ ]^ 7 3 =7 ( d² y d x² ) are respectively

Options

  1. A2,3
  2. B3,3
  3. C2,2
  4. D3,2

Correct answer

A. 2,3

Step-by-step solution

We have [1+ ( d y d x )³ ]^ 7 3 =7 ( d² y d x² ) Raising both sides to power of 3 , we get [1+ ( d y d x )³ ]⁷=(7)³ ( d² y d x² )³ Hence order =2 , degree =3
