Represent on the real number line.

Step-by-step solution

Using Pythagoras theorem, OB = Hence, take OA = 1 unit on the number line and AB = 1 unit, which is perpendicular to OA. With O as centre and OB as radius, we draw an arc to intersect the number line at P. Then P corresponds to on the number line as shown in figure. Clearly, OP = OB =
