Question

represent√5on the no. line​

Answer 1

Answer:

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= sqrt of 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.
