How to represent under root 9 on number line

1.	How to represent under root 9 on number line
Answer» Though I know you would\'ve been confused with what I wrote but at least I had some typing exercise... use spiral method, it\'s easier... just follow the steps: draw a 1cm line, name it AB. now draw a perpendicular to AB of 1 CM and name it BC. Now connect those to lines and name them CA, This will be under root 2. Now again draw a perpendicular to CA of 1 cm and join it, this is under root 3. Keep doing this till you reach under root 9. Then, use a compass and put the pointer on point A. Now, if you want to directly represent under root nine, then place the pencil(which is connected to the compass) on the point at which under root 9 starts and draw an arc. Extend the line AB and the place where the arc and the line meet is under root 9. There are two methods: spiral method or geometrically
