Solution
3
We have,
\[\left[ 5 + \left( \frac{dy}{dx} \right)^2 \right]^\frac{5}{3} = x^5 \left( \frac{d^2 y}{d^2 x} \right)\]
Taking Cube power on both sides, we get
\[ \left( 5 + \left( \frac{dy}{dx} \right)^2 \right)^5 = x^{15} \left( \frac{d^2 y}{d^2 x} \right)^3 \]
\[\text{ The highest order derivative is }\frac{d^2 y}{d^2 x}\text{ and its power is 3 . }\]
Hence, the degree is 3.
