Question

how to represent root 15 on no. line

Answer 1

to represent root 15 we use pythagoras theorem
in a right angled triangle we will take base as 1 and hypotenuse as 4 
thus the perpendicular root will be 15..

to draw the root 15,draw a line BC =1 unit draw BA perpendicular to BC.
from C cut an arc of length 4 units,let it itersect at the perpendicular at A.
Thus AB =root 15..




Hope this helps u.....


GOOD LUCK!
