find the total work done in moving a parcticle in a force field given by F = 3x * y deg - 52 deg + 10xk along the x = 1 + t ^ 2 y = 24 ^ 2 z = f ^ 3 from 1/x = 1 + f = 2

To find the total work done in moving a particle in a force field \(\mathbf{F}\), we need to compute the line integral of the force field along the path given by the parametric equations:

\[
\mathbf{F} = 3x \mathbf{i} + y \mathbf{j} - 52 \mathbf{k} + 10x \mathbf{k}
\]

And the path:

\[
x = 1 + t^2, \quad y = 24^2, \quad z = f^3
\]

The work done \(W\) is given by:

\[
W = \int_C \mathbf{F} \cdot d\mathbf{r}
\]

Here, \(d\mathbf{r}\) is the differential element of the curve, and \(\mathbf{F}\) is the force field. To compute this:

1. **Parameterize the Path**:  
   - From the given \(x = 1 + t^2\), \(y = 24^2\), and \(z = f^3\), assume \(x\) as the parameter: \(t\) as \(x\).
   - The path in terms of \(x\) can be written as:
     \[
     x = x, \quad y = 24^2 = 576, \quad z = (x - 1)^{3/2}
     \]
     
2. **Determine the Differential \(d\mathbf{r}\)**:  
   The differential of the position vector \(\mathbf{r}(x)\) is:
   \[
   d\mathbf{r} = \frac{d\mathbf{r}}{dx} dx
   \]
   Since \(\mathbf{r}(x) = x \mathbf{i} + 576 \mathbf{j} + (x-1)^{3/2} \mathbf{k}\),
   \[
   d\mathbf{r} = \mathbf{i} dx + 0 \mathbf{j} + \frac{3}{2}(x-1)^{1/2} \mathbf{k} dx
   \]

3. **Calculate the Dot Product \(\mathbf{F} \cdot d\mathbf{r}\)**:  
   The force field is given by:
   \[
   \mathbf{F}(x, y, z) = 3x \mathbf{i} + 576 \mathbf{j} - 52 \mathbf{k} + 10x \mathbf{k}
   \]
   Substituting into the dot product:
   \[
   \mathbf{F} \cdot d\mathbf{r} = (3x)(dx) + 0 + \left(-52 + 10x\right) \left(\frac{3}{2}(x-1)^{1/2}\right) dx
   \]

4. **Integrate the Dot Product**:  
   The integral limits for \(x\) are from the starting point (\(x=1\)) to the ending point (calculated from \(1/x = 1 + f = 2\), hence \(x = 1/3\)):
   \[
   W = \int_{1}^{1/3} \left[3x + \frac{3}{2}(-52 + 10x)(x-1)^{1/2}\right] dx
   \]

Let's evaluate this integral to find the total work \(W\). 

(Note: There may be some mistake in your query interpretation about the limits and path so correct any error.)
