The correct Answer is:
To determine the order and degree of the given differential equation
\[
\frac{d^4y}{dx^4} = y + \left(\frac{dy}{dx}\right)^4,
\]
we will follow these steps:
### Step 1: Identify the highest derivative
The first step is to identify the highest derivative present in the equation. In this case, we have:
- \(\frac{d^4y}{dx^4}\) which is the fourth derivative of \(y\).
- \(\frac{dy}{dx}\) which is the first derivative of \(y\).
The highest derivative is \(\frac{d^4y}{dx^4}\), which indicates that the order of the differential equation is 4.
### Step 2: Determine the order
The order of a differential equation is defined as the highest order of derivative present in the equation. Since the highest derivative here is the fourth derivative, we conclude that:
\[
\text{Order} = 4.
\]
### Step 3: Identify the degree
Next, we need to find the degree of the differential equation. The degree of a differential equation is the power of the highest order derivative when the equation is expressed as a polynomial in derivatives.
In our equation, we can see that:
- The highest order derivative \(\frac{d^4y}{dx^4}\) appears to the power of 1.
- The term \(\left(\frac{dy}{dx}\right)^4\) is not affecting the degree of the highest derivative since it is not in the same polynomial form as \(\frac{d^4y}{dx^4}\).
Since the highest order derivative \(\frac{d^4y}{dx^4}\) is raised to the power of 1, we conclude that:
\[
\text{Degree} = 1.
\]
### Final Conclusion
Thus, the order and degree of the given differential equation are:
- **Order**: 4
- **Degree**: 1
