Sqrt(4) is not a surd, because sqrt(4) is + or - 2, which is rational. On the other hand, sqrt(2) is a surd, and that's because the square root of two is irrational.
A surd is a number that cannot be changed into a fraction. They go on infinitely without any pattern.

What is an infinite surd?
Infinite surd is a term used in mathematics. The definition of an infinite surd is a never ending irrational number with an exact value that would be left in square root form.
Why was an irrational number called a 'surd' as opposed to an 'irrat'?
The term surd traces back to al-Khwārizmī, who referred to rational and irrational numbers as audible and inaudible, respectively. This later led to the Arabic word "أصم‎" (asamm, meaning "deaf" or "dumb") for irrational number being translated into Latin as "surdus" (meaning "deaf" or "mute").
Is every irrational a surd?
sqrt(8) = /(8) = sqrt(2 x 4) => sqrt(2 x4) = sqrt(2) X sqrt(4) => sqrt(2) X 2 => 2*sqrt(2) '2' is a Prime Number. The 'Square Roots' of prime numbers are IRRATIONAL. sqrt(2) = 1.414213562.... ( to infinity). This makes it irrational . Hence 2 * 1.414213562.... = 2.828427125..... (Which is also irrational). NB A rational number multiplied to an irrational number produces an irrational result,.
Is the sum of irrational roots irrational?
Not always. For example: sqrt(2)+(-sqrt(2))=0 which is not irrational.
The square root of 50 is it rational or irrational?
The square roots of 50 are irrational.
In math what is the expression containing irrational roots?
Surd
What is a mathematical expression involving irrational roots?
surd
Can you give one example for surd which is not irrational?
It is impossible to have a surd that is not irrational. Surds are defined to be an irrational number (square root of a number).
Are all irrational numbers are surds?
Yes. The definition of a surd is "an irrational number"
What is unique surd meant by?
A unique surd refers to a specific type of irrational number that cannot be simplified into a more basic radical form. It typically involves square roots or other roots that cannot be expressed as a ratio of integers. For example, √2 is a unique surd, as it cannot be simplified further. The term emphasizes the distinctiveness of certain surds in mathematical expressions.
Are surd's rational?
No because surds are irrational numbers
Is root 2 a surd?
Yes the square root of 2 is a surd which is an irrational number that can't be expressed as a fraction.
What does surd mean in maths?
A surd is an irrational number that can't be expressed as a fraction as for example the square root of 2
What is the mathematical definition of surd?
An irrational number such as the square root of 2
What is an infinite surd?

Is square root of pi a surd?
Yes. A surd is any irrational number that can be expressed as the root of another number. As pi is a number, although it is a transcendental and hence irrational, the square root of pi is still an irrational number that can be expressed as the square root of another number.
