1.414

The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414.

The square root of 2 rounded up to 10 decimal places is 1.4142135624. It is the positive solution of the equation x = 2.

All negative numbers will have a complex number as their square root. A complex number is a number multiplied by i. i is the "imaginary" square root of -1. It's called imaginary, but it does exist to mathematicians.

The square root of 2 is "irrational" (cannot be written as a fraction) ... because if it could be written as a fraction then we would have the absurd case that the fraction would have even numbers at both top and bottom and so could always be simplified.

Because √2 is not an integer (2 is not a perfect square), √2 must therefore be irrational. This proof can be generalized to show that any square root of any natural number that is not a perfect square is irrational.

In order to simplify a surd:

- Find a square number that is a factor of the number under the root.
- Rewrite the surd as a product of this square number and another number, then evaluate the root of the square number.
- Repeat if the number under the root still has square factors.

So to cancel time algebraic fraction what we're going to do is we're going to factorize theMoreSo to cancel time algebraic fraction what we're going to do is we're going to factorize the numerator. And factorize the denominator. If we can and then cancel down ok let's have a look at an example.

A surd is an expression that includes a square root, cube root or other root symbol. Surds are used to write irrational numbers precisely – because the decimals of irrational numbers do not terminate or recur, they cannot be written exactly in decimal form.

pie is not a surd. though it is irrational but it is a non algebraic irrational number or transitional number. also it is no definite decimal value. therefore pie is not a surd.

Introducing standard index form

Standard index form is also known as standard form. A number is said to be written in standard form when it is written as A × 10 n , where. is a number greater than or equal to , but strictly less than , and. tells us how many places to move the decimal point.
