The degree and order of the differential equation 1 + d y d x 3 7 3 = 7 d 2 y d x 2 respectively are

Options

  1. A3 and 7
  2. B3 and 2
  3. C7 and 3
  4. D2 and 3

Correct answer

B. 3 and 2

Step-by-step solution

The given differential equation can be written as [ 1 + ( d y d x ) 3 ] 7 = 7 3 ( d 2 y d x 2 ) 3 ⇒ order = 2, degree = 3
