To find the vector equation of a plane in \( \mathbb{R}^4 \) that passes through the point \( p = (1, 3, 5, -2) \) and has the direction vectors \( v = [0, 2, -2, 3] \) and \( w = [1, 1, -1, 1] \), you can use the following vector equation:

\[
x = p + sv + tw
\]

Where:
- \( x \) is any point on the plane,
- \( p \) is the given point on the plane \( (1, 3, 5, -2) \),
- \( v \) and \( w \) are direction vectors, and
- \( s \) and \( t \) are scalar parameters.

Now, breaking this down step by step:

1. The position vector of the point \( p \) is:
   \[
   p = [1, 3, 5, -2]
   \]

2. Add the direction vector \( v \) scaled by \( s \):
   \[
   s[0, 2, -2, 3] = [0, 2s, -2s, 3s]
   \]

3. Add the direction vector \( w \) scaled by \( t \):
   \[
   t[1, 1, -1, 1] = [t, t, -t, t]
   \]

Thus, the vector equation for the plane is:

\[
x = [1, 3, 5, -2] + s[0, 2, -2, 3] + t[1, 1, -1, 1]
\]

Expanding this:

\[
x = [1, 3, 5, -2] + [0, 2s, -2s, 3s] + [t, t, -t, t]
\]

Final answer:

\[
x = [1 + t, 3 + 2s + t, 5 - 2s - t, -2 + 3s + t]
\]

This is the vector equation of the plane in \( \mathbb{R}^4 \).
