Question

The order and degree of the differential equation `[1 + ["dy"/"dx"]^3]^(7/3) = 7 (("d"^2"y")/"dx"^2)` are respectively.

Options

• 2, 1

• 1, 2

• 3, 2

• 2, 3

Answer 1

2, 3

Explanation:

Given differential equation.

`[1 + ["dy"/"dx"]^3]^(7/3) = 7 (("d"^2"y")/"dx"^2)`

`(1 + ("dy"/"dx")^3)^7 = 7^3 (("d"^2"y")/"dx"^2)^3`

Clearly order = 2 degree = 3
