उत्तर

`(("d"^3"y")/"dx"^3)^(1/2) - ("dy"/"dx")^(1/3) = 20`

`(("d"^3"y")/"dx"^3)^(1/2) = 20 + ("dy"/"dx")^(1/3)`

Taking power 6 on both sides.

`[(("d"^3"y")/"dx"^3)^(1/2)]^6 = [20 + ("dy"/"dx")^(1/3)]^6`

`(("d"^3"y")/"dx"^3)^3 = [20 + ("dy"/"dx")^(1/3)]^6`

∴ The given differential equation is radical and fraction free and its highest order is 3.

∴ Order = 3, degree = 3
