When we can't simplify a number to remove a square root (or cube root etc) then it is a surd. Have a look at these examples (including cube...

Mathematics Surd (mathematics), an unresolved root or sum of roots Radical symbol, the notation for a root formerly, an irrational number in general

Both surd and its more common cousin absurd come from the Latin word surdus, meaning "unhearing, deaf, muffled, or dull." Absurd traveled through Middle French before arriving in English in the early …

What Is Surds? A surd is defined as an irrational root that cannot be expressed exactly as a fraction or terminating/repeating decimal. For example, numbers like √2, √7, or ∛5 are all surds because their …

Is root of 4 a surd? Square root of 4, √4 is not a surd. √4 = 2 and 2 is a whole number.

A surd is any number whose nth root (square root, cube root, etc.) cannot be simplified so as to remove the radical sign.

Well, 2 x 121 is 242 and we can take the square root of 121 without leaving a surd (because we get 11). Since we cannot take the square root of a larger number that can be multiplied by another to give …

A surd is a number that has been square-root. In general, such roots are irrational; however, irrational numbers also include other numbers that cannot be expressed as the root of a rational number.
