A surd is when an irrational number (a non square number under a square root sign) is simplified for accuracy and ease of legibility.


√5 x √2 = √10

There are no such rational numbers as Square root of five or two so when we multiply them (as shown in the exampke above) we show the answer in surd form for simplicity, accuracy and legibility.
