The order is the highest numbered derivative in the equation with no negative or fractional power of the dependent variable and its derivatives, while the degree is the highest power to which a derivative is raised.

In this question we will be raising both the sides to power 6 so as to remove the fractional powers of derivatives of the dependent variable y

So, the equation becomes as

1+=

So, in this the order of the differential equation is 2 and the degree of the differential equation is 2.

In a differential equation, when the dependent variable and their derivatives are only multiplied by constants or independent variable, then the equation is linear.

So, in this question the dependent variable is y and the term is multiplied by itself and many other are also, so the given equation is non-linear.
