Check the highest order of derivate to find the order and check the power of highest derivative to find degree.

Given:

            \left ( {{y}'}'' \right )^{2}+\left ( y{}'' \right )^{3}+\left ( {y}' \right )^{4}+y^{5}=0

Solution:

                \left ( {{y}'}'' \right )^{2}+\left ( y{}'' \right )^{3}+\left ( {y}' \right )^{4}+y^{5}=0

Highest order derivative=3

\therefore           Order=3

Degree=power of\left ( {{y}'}'' \right )^{2}

\therefore           Degree=2
