a surf is a rational number of a irrational numbers
Answers
Answer:
By definition , a surd is an irrational root of a rational number.So now we know that surds are always irrational and they are always roots.
For example , square root of 2 is a surd since 2 is rational and square root of 2 is irrational
similarly, cube root of 9 is also a surd since 9 is rational and cube root of 9 is irrational.
On the other hand, is not a surd even though is irrational, because is not rational
Answer:
Every surd is an irrational, but every irrational need not be a surd.
