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

Options

  1. A2,1
  2. B2,3
  3. C1,2
  4. D3,2

Correct answer

C. 1,2

Step-by-step solution

(D) We have [1+ [ d y d x ]³ ]^ 7 3 =7 d² y d x² Cubing both sides, we get [1+ [ d y d x ]³ ]⁷=7 [ d² y d x² ]³ Hence order is 2 and degree is 3 .
