Surds are normally irrational numbers.

No. Surds are a part of maths, and are the opposite of powers.

Roots that are irrational are called surds. There are irrational numbers that are not surds since they are not roots of any equation. For example, Pi. Rational roots, such as square root of 4, are not surds.

Irrational numbers

the limit does not exist

No, surds can never be negative.

Whoever it was who discovered that if you had a square whose sides were one unit long, the lengths of its diagonals were sqrt(2) - surds!

Irrational number are NOT called surds. For example, pi is irrational but it is not a surd.Surds are a very small subset of irrational numbers.

No because surds are irrational numbers

They define irrational numbers

How one understands surds depends on the person. If you would like to know what surds are, or have help understanding surds A surd is an unresolved radical, meaning that it is a root with the radical sign still on it. It is easier (and more accurate) to express it this way than writing it out for many numbers if the root is irrational. The concept of irrational numbers (which is what surds are, usually) can be confusing. In short, they are numbers that are not rational, that is, they cannot be written as a fraction. When using surds in math, you treat them just as you would a written out number.

The concept of surds, is that if a number isn't divisible, and has too many decimal places, it can be left as a surd, to make it less complicated to work out
