Question

Represent√5 on a number line and write the calculation

Answer 1

Answer:

A=25

Step-by-step explanation:

I hope you understand

Answer 2

Answer:

Draw number line as shown in the figure. Let the point O represent 0(zero) and point A represents 2. Draw perpendicular AX at A on the number line and cut-off arc AB=1unit.

We have OA=2 units and AB=1unit

Using pythagoras theorem, we have,

OB² =OA²+AB²

OB²=(2) ²+(1)²

OB= √5

​

Taking O as the centre and OB= √5 as radius draw an arc cutting real line at C. Clearly, OC=OB= √5
