First we need to make in into a polynomial equation
so take the cube on both sides
order =3
degree= 3
hope it helps

Di where are the steps ?
you need them i can do that
there is only one step to cube it so i skipped that i just wrote cube both sides
you dont need to open the cube on lhs
Ok thank you Shubhi Di.
my pleasure

Hello,
Highest order derivative is d³y/dx³,
So order is 3.
Now for degree: take cube both sides
[(dy/dx)² + d²y/dx²]⁷ = (d³y/dx³)^3
since in LHS by expanding the expression order do not change. Now look at RHS ,it has now power three.
power of highest order derivative is degree.
So, Order is 3 and degree is 3.
Hope it helps you.
