Find the distance between the points `P (1, -3, 4)`and `Q ( -4, 1, 2)`.

Explanation

To find the distance between the points \( P(1, -3, 4) \) and \( Q(-4, 1, 2) \), we will use the distance formula in three-dimensional geometry. The distance \( d \) between two points \( P(x_1, y_1, z_1) \) and \( Q(x_2, y_2, z_2) \) is given by the formula:

\[ d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2} \]
