entire surds examples
Answers
Example: √4 (square root of 4) can be simplified (to 2), so it is not a surd! The surds have a decimal which goes on forever without repeating, and are Irrational Numbers. In fact "Surd" used to be another name for "Irrational", but it is now used for a root that is irrational.

square root (or cube root etc) then it is a surd.
Example: √2 (square root of 2) can't be simplified further so it is a surd
Example: √4 (square root of 4) can be simplified (to 2), so it is not a surd!
Have a look at some more examples:

not?
√2 √2 1.4142135...(etc) Surd
√3 √3 1.7320508...(etc) Surd
√4 2 2 Not a surd
√¼ ½ 0.5 Not a surd
3√11 3√11 2.2239800...(etc) Surd

5√3 5√3 1.2457309...(etc) Surd
