**Can √ 2 be simplified?**

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.

### Is the square root of 2 is 1?

The square root of 2 is an irrational number, so cannot be represented as a fraction in the form pq where p,q are integers. It can be represented as a continued fraction, written: √2=[1;¯2]=1+12+12+12+12+12+…

### Why is √ 2 an irrational number?

Specifically, the Greeks discovered that the diagonal of a square whose sides are 1 unit long has a diagonal whose length cannot be rational. By the Pythagorean Theorem, the length of the diagonal equals the square root of 2. So the square root of 2 is irrational!

**What is the order of root 2?**

A surd with index of root 2 is called a second order surd or quadratic surd. The surds which have the indices of root 2 are called as second order surds or quadratic surds. For example√2, √3, √5, √7, √x are the surds of order 2.

## Is 2 a square number?

Informally: When you multiply an integer (a “whole” number, positive, negative or zero) times itself, the resulting product is called a square number, or a perfect square or simply “a square.” So, 0, 1, 4, 9, 16, 25, 36, 49, 64, 81, 100, 121, 144, and so on, are all square numbers.

## Is the square root of 2 A whole number?

It is actually easy to see why some numbers are irrational. A famous example is the square root of 2, which is roughly 1.4142, and denoted √2. If √2 were rational, it must be expressible in the form a/b, where a and b are natural numbers (that is, whole numbers). We can immediately conclude that a2 is an even number.

**Can Root 2 be written as a fraction?**

Root 2 is an irrational number as it cannot be expressed as a fraction and has an infinite number of decimals. So, the exact value of the root of 2 cannot be determined.

### Why is the square root of 2?

Geometrically, the square root of 2 is the length of a diagonal across a square with sides of one unit of length; this follows from the Pythagorean theorem. It was probably the first number known to be irrational….Square root of 2.

### How do you write root 2?

The square root of 2 or root 2 is represented using the square root symbol √ and written as √2 whose value is 1.414. This value is widely used in mathematics.

**Is square root of 2 rational?**

Proof: √2 is irrational.
