3. Show how √5 can be represented on the number line.
Step 1: On the number line, take 2 units from O and represent the point as A. Step 2: At point A, draw a perpendicular and mark B such that AB = 1 unit. Step 3: Now, with O as the center and OB as radius, draw an arc to cut the number line at C. Step 4: Point C represents √5 on the number line.
