Which of the following shows the proper steps to construct a perpendicular bisector of a segment through any point?

To do it with a straightedge, create two points on the line. Then, extend your compass while placing it on a point to a little more than halfway between the segment. Draw an arc and repeat on the other side. Make sure the arcs intersect, and mark the points of intersection. Draw a line through those.

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
