Question

express root 7 on the number line. Help me fast​

Answer 1

draw a number line.

keep your compass on unit 2, take smaller distance than 1 unit.

now draw a semicircle.

keep your compass on the right end of the circle and draw a chop on the semicircle. use the same distance used while drawing the simecircle.

now keep your compass on the chop just made and draw another chop on the semicircle.

keep your compass on the chops made and draw a cross chop, it should come exactly above unit 2.

draw a perpendicular line cutting through the chop.

take 1 unit distance on your compass and draw a chop on the perpendicular line.

now join unit 0 with this chop.

the line made, mark it as root 5.

repeate the whole process twice to get root 7.

^it's a bit complicated but I hope this helps.
