    Step-by-step explanation:
    I assume the square root always goes across the whole expression, right ?
    the calculation you provided is correct. there was nothing done wrong here.
    so, I guess the mistake must have been made with the coordinate numbers in the first place.
    since I don’t see any graphic or the coordinates of the points, where clearly the distance has to be calculated, I cannot give you the details.
    based on the calculation, the points would have been
    A (2, -4)
    B (6, 1)
    and I guess the original coordinates must be different somehow.
    otherwise it would all be correct.
