Let l be the line passing through the point p(−4, −4, 5) with direction vector d=[1, 3, 2]t. find the shortest distance d from the point p0(−4, −1, −1) to l, and the point q on l that is closest to p0. use the square root symbol '√' where needed to give an exact value for your answer.

d is the answer i came up with
