  1. Draw a number line and mark 0, 1, 2, 3, .etc.
  2. Mark 0 as point O and 2 as B.
  3. Now from B, draw a perpendicular AB of length 1 unit.
  4. Join OA.
  5. Again From A, draw a perpendicular AC of length 1 unit.
  6. Join OC.
  7. Again From C, draw a perpendicular CD of length 1 unit.
  8. Join OD.

Keeping this in consideration, how do you find the root of 7?

To find the square root of 7 we can use the long division method which is simple and easy. Therefore, the value of the square root of 7 is 2.64.

Subsequently, question is, how do you root 4 on a number line?

  1. Draw a no. line and take B at 0 and C at 1 i.e. take BC = 1 units with B at 0.
  2. Draw AC perpendicular to BC with length 1 units .
  3. Join AB and use Pythagoras theorem to find the length of AB which will be ✓2.
  4. Keep pointer of compass at B and taking radius as BA draw an arc cutting the number line in point D. AB = BD =✓2.

Subsequently, one may also ask, what is the value of root under 7?

How do you draw a square root of 3 without line?

Now, again draw a perpendicular at point B of length BC= 1 unit and join the points O and C. Again by pythagoras theorem we get OC = root 3. Then by compus taking radius =OC, draw an arc so that it cuts the number line at D. Then the distance OD will be the square root of 3.
