Question

Locate root 10 on number line with steps

Answer 1

First draw no line
as2=root 4
3=root 9
4=root16
therefor, root10 on line will be between root 9&10

Answer 2

to locate √10 on number line follow the steps.                let 3cm = 1 unit1] √10 = √3²+1²2]draw a number line OC such that OA=AB=OC=1 unit3] draw a perpendicular line from C of 1 unit [as √10 = √3²+1² ] and name the point as C4] join O and C  it will form a triangle        by pythagoras theorem             OC = √10           now taking the radius of OC in compass draw an arc touching the number line . and that point will be   √10 .
