Intuitively 20.5is between 10.5 and 40.5. Since these values are 1 and 2 respectively 20.5 must be between 1 and 2. However since the roots to each of these numbers can be either posative (+) or negative (-) the roots can lie on either side of the 0. The answer is then that the root of two can be greater than -2 and less than -1, or less than +2 and greater than +1.
Root 2 ka number line
about 1/3 of the distance from 1 to 2
The square root of 648 is 18 times the square root of 2. 648 has no perfect square root.
The square root of 4 is 2. 2 is a rational number so they square root of 4 is rational.
The square root of a number is a number which when multiplied by itself will result in the original number. So the square root of 4 is 2, because 2 times 2 equals 4. For an easy square root like that you can work it out in your head, but for harder questions you should use a calculator. Your calculator will have a button to press to calculate the square root of a number.
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.

The square root of 2 is 1.141..... is an irrational number
Sometimes the square root of a positive number can be irrational, as in the square root of 2 (which is a non-perfect square number), but sometimes it is a rational number, as in the square root of 25 (which is a perfect square number).
Square root of 2= 1 You should know this idiots!
Between 2 and 3.
The square root of 2 is an irrational number
The square root of 2 squared is 2. sqrt(22)=2 The square root function and the exponent 2 and opposite function and cancel each other out. 22=4 sqrt(4)=2 =>sqrt(22)=2 What is the (square root of 2) squared - If you take the square root of a number then square it the answer is the number itself, so the answer is 2! What is the square root of (2 squared) - Looking at the question another way, if you take a number and square it, the square root of the resulting answer is the number itself, so the answer is 2! Unless, of course, this is a trick question . . . ivj
