A surd is the square root of an integer (whole number), e.g. square root of 2 is a surd. Pi is not the square root of an integer so not a surd, just an irrational number
No because it is 3
[square root (78)] squared = 78. There is not a surd from for an integer.
If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.

Surds are irrational numbers and 27 is a rational number but if you mean the square root of 27 then it is an irrational number and expressed as a surd it is 3 times square root of 3.
If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.
no
Yes the square root of 2 is a surd which is an irrational number that can't be expressed as a fraction.
yes
Yes.
Expressed as a surd, sqrt(75) + sqrt(48) = 9 sqrt(3).
Surds are irrational square root numbers that cannot be solved but they can be simplified. For example the square root of 12 can be simplified to 2 times the square root of 3.
The square root of 82 cannot be reduced as a surd.
