Yes the square root of 2 is a surd which is an irrational number that can't be expressed as a fraction.
The square root of 128 can be simplified in surd form as follows: ( \sqrt{128} = \sqrt{64 \times 2} = \sqrt{64} \times \sqrt{2} = 8\sqrt{2} ). Thus, the square root of 128 in surd form is ( 8\sqrt{2} ).
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.

An irrational number such as the square root of 2
If the value of the surd is positive, then it will be another surd. Otherwise it will be a complex number.
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..

[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).
root 200 = root 2 multiplied by root 100 root 100 = 10 root 200 = 10 root 2
That is the only way to write it exactly.
