Question

represent √5 on number line​

Answer 1

Answer:

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,

OB  

2

=OA  

2

+AB  

2

 

OB  

2

=(2)  

2

+1  

2

=5

OB=  

5

​  

 

Taking O as the centre and OB=  

5

​  

 as radius draw an arc cutting real line at C. Clearly, OC=OB=  

5

​  

.

Hence, C represents  

5

​  

 on the number line.Step-by-step explanation:
