Question

a number is an irrational but not a surd​

Answer 1

Answer:

Irrational numbers like π and e, which are not the roots of algebraic expressions, are not surds.

Every surd is irrational but not all irrational numbers are surds. The surds in mathematics are \pi and e and they are irrational too. On the other hand \sqrt{2} will give you an irrational number but this number is not called surd.

Answer 2

Step-by-step explanation:

All surds are irrationals but all irrational numbers are not surds. Irrational numbers like π and e, which are not the roots of algebraic expressions, are not surds.
