Represent the irrational number, sqrt(7) on the numberline.
In order to do this, we need to know what number sqrt(7) is! It's not a nice number either, but we can figure it out.
Some perfect square number that can help us
0 * 0 = 0
1 * 1 = 1
2 * 2 = 4
3 * 3 = 9
4 * 4 = 16
sqrt(7) is asking, what number times itself is 7?
Let's use our perfect square numbers to help.
? * ? = 7
Where does this fit in on our list of perfect square numbers?
2 * 2 = 4
? * ? = 7
3 * 3 = 9
7 lies between 4 and 9! This means that sqrt(7) is somewhere between...
That's right, 2 and 3.
In fact, 7 is closer to 9 (2 away) than 7 is from 4 (3 away). This means, sqrt(7) is closer to 3 than it is to 2 on the numberline.

i do not know how to do it please tell me how to do it
Negative square root is -√Square root of negative one is i.
When dealing with real numbers, you cannot take the square root of a negative number. The concept of the imaginary number was created to handle the square root of a negative number.That's almost like saying "when dealing with numbers bigger than 10, you cannot take the square root of 4. If what you are dealing with does not represent a number, then you cannot find its square root.
The radical symbol ( √ ) followed by a line above what's in the radical, designates positive square root.
Mathematicians decided that, since the square root of a negative number does not exist, they would use the first letter of "imaginary" to represent this "value".
take a no. line

You can't find the square root of -10 because you can't find the square root of any negative number. But we have something to represent the answer, i, i is a imaginary number.

It represents a number. The number is the one which, when you multiply it by itself, the product is 'n'.
It is no tpossible to find the square root of an unknown number. You can, however, represent it as x0.5 or √x so that the value of the square root can be evaluated when the value of x is known.
It represents another number that, when multiplied by itself, gives the number you started with. For example, the square root of 2.25 is 1.5 because 1.5*1.5 = 2.25
The 'radical': √
friends,root 10 is according to our pythagores thoream.root 10=square of 3 and square of 1 can be represented on a number line.
it is less than 4 greater than 5
By root, I think you mean square root. The square root of 2 is approx. 1.414. The square root of 9 = 3, so this goes exactly at 3 on the number line. Square root 2 will be less than 1/2 way between 1 and 2 on the number line.
