|
Answer» LOCATING √5 on number line : Here 5 = 2² + 1¹ ..............[ See the ATTACHED image (I) √5 ].......... So, draw a line a right angled OAB, in which OA = 2 units and angle OAB = 90° By USING Pythagoras theorem, we get Taking OB = √5 as radius and point Pad centre, draw an arc which meets the number line point P on the positive SIDE of it. Hence, it is clear that point P represents √5 on the number line. |
