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..

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.

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

[square root (78)] squared = 78. There is not a surd from for an integer.

No. It is not a criminal or civil offence!

No.

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.

A surd in the form aâˆšb cannot, in general, be simplified.

no

[square root (78)] squared = 78. There is not a surd from for an integer.
