It is a number that is approximately equal to 1.4142. Since it is an irrational number, any decimal representation must be an approximation. However, if you have a pair of compasses, it is not that difficult to mark sqrt(2) on the number line.
- Draw a line at 1 that is vertical to the number line.
- Put the compass point at 1, radius = distance from 1 to 0 and draw an arc to cut the vertical line at X.
- Put the compass point at 0, radius = distance from 0 to X and draw an arc. This will cut the number line at sqrt(2).

How draw square root of 2 on number line?
It'll be between 1 and 2
Where do you put the square root of 2 on the number line?
about 1/3 of the distance from 1 to 2
What is the symbol used to represent a negative square root of a number?
Negative square root is -√Square root of negative one is i.
How are rational exponents related to radicals?
You can represent a radical with a rational exponent. For example the nth root of a number m can be written as m1/n . If n was 2 for example, then it is the square root. So square root of 3 or radical 3 is written sqrt(3) or 31/2 .
How do you place the square root of 5 in a number line?
At the number 2, draw a vertical line (perpendicular to the number line) and mark a distance of 1 unit on this line. Call this point X The distance from 0 to X is sqrt(5). Put a compass with its point at 0 and the pencil at X, and then draw an arc to cut the number line. That will be sqrt(5) on the number line.
