Question

represent under root 26 on number line

Answer 1

First of all we will draw 26cm line and will extend it by 1 cm so it will become of 27 cm ok . You have to Mark A at the starting point and B to where 26cm ends and C to the last 1 cm ok.
Now from point A and from C draw a perpendicular bisector and from this we will get the midpoint O now from O draw a semi circle and from B join to the semi circle vertically and now draw a line of any length like 8 cm or of any length and take the length of that line and cut on New line and this is our under root 26
