A surd is an irrational number that can't be expressed as a fraction as for example the square root of 2
Expressed as a surd, the square root of 28 is equal to 2 root 7.
That is the only way to write it exactly.
There's no reason why it should be, it's 2, end of story.
Yes.
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

If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.
An irrational number such as the square root of 2
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..
Expressed as a surd, the square root of 28 is equal to 2 root 7.
root 200 = root 2 multiplied by root 100 root 100 = 10 root 200 = 10 root 2
[square root (78)] squared = 78. There is not a surd from for an integer.
Expressed as a surd, sqrt(98) + sqrt(2) = 8 sqrt(2).
no
