Question

/ Show how √5 can be represented on the number line.​

Answer 1

Answer:

as graph (or) algebra ....... Say that first p2

Answer 2

Answer:

Step-by-step explanation:

Draw a number line and take point O and A on it such that OA = 1 unit. Draw BA ⊥ OA as BA = 1 unit. Join OB = √2 units.

Now draw BB1 ⊥ OB such that BB1 =1 unit. Join OB1 = √3 units.

Next, draw B1B2⊥ OB1such that B1B2 = 1 unit.

Join OB2 = units.

Again draw B2B3 ⊥OB2 such that B2B3 = 1 unit.

Join OB3 = √5 units.

Take O as centre and OB3 as radius, draw an arc which cuts the number line at D.

Point D

represents √5 on the number line.
