Surds are based on roots.
Root 8 can be split into root 4 and root 2; as there's a root to 4, get that number, and multiply it by the remaining root.
So root 8 = 2 root 2.
Root 40 would be 2 root 10
Root 48 would be root 4, root 4, root 3
Root 48 = 4 root 3.

i did
it is a mathematics source and is hard to explain
Yes the square root of 2 is a surd which is an irrational number that can't be expressed as a fraction.
A surd is an irrational number that can't be expressed as a fraction as for example the square root of 2

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.
=See the section in this article about that topic. http://en.wikipedia.org/wiki/Set_(mathematics)

Yes it is a surd
If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.
'pi' is not a 'surd' because it is not a 'square root' of any number. 'pi' is an IRRATIONAL number. Irrational numbers are those were the decimals go to infinity AND the decinal digits are not in any regular order. pi = 3.141592654.... (recur to infinity and no regular order0. 'pi' in surd form is sqrt(pi) = sqrt(3.141592654....) = 1.772453851..... (which is also irrational). In school/college etc., you are given 'pi = 3.14 , 3.1416 , 22/7' Tese are only APPROXIMATIONS for ease of calculating. 'Super Dupa' computers have calculated 'pi' to at least 50 billion places and still going. NB A decimal number such as 1.33333.... is NOT irrational. It is RATIONAL , because it can be converted to a ration/quotient/fraction. Irrational numbers cannot be converted to an exact value 'ratio/quotient/fraction'. Notice the decimal digits are in a regular order of '3'....
true
I am pretty sure that the cube root of negative seven is a surd. I checked on the calculator.......and it showed a negative number.....??I think when it is not a surd...it's supposed to say error, so the number probably means that it is a surd..
No. It is not a criminal or civil offence!

NO!!!! 'pi' is an IRRATIONAL number. Casually, an irrational number is one that recurs to infinity, AND there is NO regular order in the decimal digits. e.g. pi = 3.141592..... but pi ~ 3.14, or 3.1416, or 22/7 ( these are only approximations (~)). However, 3.33333... is RATIONAL because, whilst the decimals go to infinity, they are are in a regular order of '3'.
