    The degree of differential equation \[\frac{{{d}^{2}}y}{d{{x}^{2}}}+{{\left( \frac{dy}{dx} \right)}^{3}}+6y=0\]is:

    A) \[1\]                                     

    B) \[3\]

    C) \[2\]                                     

    D)  \[5\]

    Correct Answer: A

    Solution :

    Key Idea: The power of highest derivative is called a degree. Given differential equation is                 \[\frac{{{d}^{2}}y}{d{{x}^{2}}}+{{\left( \frac{dy}{dx} \right)}^{3}}+6y=0\] Here, degree is\[1\]. Note: If the given differential equation is in the form of radicals, then first we convert the radicals into integers.
