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.
