Select and write the correct answer from the given alternatives in each of the following sub-questions : The order and degree of the differential equation `[1+((dy)/(dx))^(3)]^(7//3)=7((d^(2)y)/(dx^(2)))` are respectively.A. 2,3B. 3,2C. 2,2D. 3,3

Answer» Correct Answer - A
Given equation is ,
`[1+((dy)/(dx))^(2)]^(7//3)=7((d^(2)y)/(dx^(2)))`
On cubing both sides, we get
`[1+((dy)/(dx))^(3)]^(7)=(7)^(3)((d^(2)y)/(dx^(2)))^(3)`
order = 2, degree = 3
Hence, correct answer from the given alternatives is (a).
