# Square Root of 2

Kids find it quite interesting to learn and understand more about the square root of 2. The value of the square root of 2 is 2 = 1.414. And, the value of root 2 is calculated to 10 trillion digits. For general usage, its value is used as 1.414 to make computations simple. Along with teaching the little ones about the square root of 2, engage them in learning 2 Times Table, available at Osmo. These times tables help kids understand the basic concepts of the square root of 2 in a much better way. Learning square root will enable kids to develop their mathematical skillls.

## What is the Square Root of 2?

The square root of 2 is mathematically written as 2. And, in the radical form it is written as (2)1/2 and its exponent form,(2)0.5. Moreover, the square root of 2 is rounded up to ten decimal places like 1.4142135624. It is also the positive solution of the equation x square, which is mathematically expressed as x2. During the early days, Greeks discovered a number that can never be expressed in the form of pq. Here, p and q are integers and q is unequal to 0.

## How to Find the Square Root 2?

Finding the square root of 2 is useful for the little ones when they learn geometry. For example, we have a square with a side length of 1, and the child must determine the diagonal length. Now, to determine the third side, Pythagoras Theorem can be used. The third side will be √2. Also, locate the square root of 2 on a number line. And transfer the square that was used to find √2. Name the vertices of the square and the vertex must be O at 0. As it is already found that OB=√2, use a compass with radius OB and centre O, an arc must be drawn intersecting the number line at the point P.

### Is the Square Root of 2 Rational or Irrational?

As mentioned earlier, during the early days, Greeks discovered a number that can never be expressed as pq. Here, p and q are integers, and q is unequal to 0. This is a proof that the square root of 2 is irrational. Hence, 2 is not rational, which implies that the square root of 2 is irrational. Besides, the original value of 2 is undetermined. And the value of 2 up to 50 decimal places is 1.41421356237309504880168872420969807856967187537694. Therefore, to teach the square root of 2, parents and teachers can implement new and creative activities during class hours, like Osmo’s Math Games for Kids.

### Is the Square Root of 2 a Real Number?

Yes, the square root of 2 is a real number and not an imaginary number or a complex number.

These math games for kids help them learn the square root of 2 in an easy method.

## Frequently Asked Questions on Square Root of 2

### What is the square root of 2?

The value of the square root of 2 is 1.4142135.

### Is the square root of 2 a rational or irrational number?

The square root of 2 is an infinite number because it is non-repeating and non-terminating. A number which has a non-repeating and non-terminating decimal expansion is always an irrational number. Therefore, the square root of 2 is an irrational number.
