Question

locate √3,√13,√11,√7 on the number line class 9​

Answer 1

Answer:

Draw a number line (l) and mark the points O, A, B and C such that OA = AB = BC = 1

Draw CD ⊥ l, such that CD = 1 units.

Join OC

In right ΔOCD,

OD2 = OC2 + CD2

OD2 = 9 + 1 = 10

OD = square root of 10

Taking O as centre and D as radius, draw an arc which cuts l in F
