Go to the number 4 on the number line. Draw a vertical line at this point: going up at 90 degrees to the number line. Measure 1 unit [ = the distance from 0 to 1] on this line and mark it as Y.
Take a compass and put the point at 0. Take the pencil to the point Y and draw an arc to intersect the number lie at the point X. Then X is the required point, at sqrt(17).

is under root 8 is a rational number
take a no. line
By root, I think you mean square root. The square root of 2 is approx. 1.414. The square root of 9 = 3, so this goes exactly at 3 on the number line. Square root 2 will be less than 1/2 way between 1 and 2 on the number line.
friends,root 10 is according to our pythagores thoream.root 10=square of 3 and square of 1 can be represented on a number line.
The square root of 66 is a little bit greater than 8. So, plotted on a number line, it would be just to the right of the number 8.
