It is an irrational number

The square root of 2 is an irrational number because it can't be expressed as a fraction

Yes, the square root of 2 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).

Since the square root of a number is the "number times itself that equals the original number," it makes sense that the larger the original number, then the larger the square root. The value of the square root of 2 will be greater than the value of the square root of 1.5.

The square root of 2 is 1.141..... is an irrational number

No because the square root of 2 is an irrational number that can't be expressed as a fraction.

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 (an irrational number): 1.41421356....

Finding the square root of a number is performing the opposite operation of squaring the number. In order to square a number you must multiple the number by itself. 2 x 2 = 4 so the square root of 4 is 2.

If you have a square root of a number, that means that your "square root" squared (multiplied by itself) will give you your original number. For example: * The square root of 4 is 2. * 2 x 2 is 4.

The square of any square root is equal to the number itself. For example, the square of the square root of 2 squared is equal to 2. The square root of 10 squared is equal to 10.Similarly, the square of the square root of 2 is equal to 2.

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

Any number that can't be expressed as a fraction is irrational as for example the square root of 2

The square root of 2 is an irrational number

You square the number, ie ^2. The square root is actually ^0.5, so if you square the number, you are doing ^0.5*2 = ^1, which is implicit on every number.

A square root is a number raised to the exponent (power) 1/2.

Definition of Square Root: The Square Root of a number 'X' is equal to 'A' when X=A*A By definition, the square root of a positive number has two answers, one negative and one positive, that have equal magnitudes. i.e. The square roots of 4 are 2 and -2. The Non-Negative Square Root is simply asking for the positive root.

No because it is 2 times the square root of 21 which is an irrational numberThe square root of 84 is not a rational number

there isn't. Square root of 2 can be approximated (1.41) but since it has an infinite number of decimal places then it is considered irrational. it therefore means that in algebra the square root of 2 is like a number in itself and can be written as 'root 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.

Square root of 2= 1 You should know this idiots!

The square root of a composite number is not always an irrational number. e.g. 4 is a composite number and its square root is 41/2 = 2, which is rational number.
