For the differential equation $\left[1-\left(\frac{d y}{d x}\right)^2\right]^{5 / 3}=8 \frac{d^2 y}{d x^2}$ has the order and degree
- 2 and 1
- 2 and 3
- 2 and 6
- 2 and 2
Solution
$\begin{aligned} & \left\{1-\left(\frac{d y}{d x}\right)^2\right\}^{\frac{5}{3}}=8 \frac{d^2 y}{d x^2} \\ & \Rightarrow\left\{1-\left(\frac{d y}{d x}\right)^2\right\}^5=8^3\left(\frac{d^2 y}{d x^2}\right)^3 \\ & \text { order }=2 \text { and degree }=3\end{aligned}$
