Question

What are surds? how many types of surds are there?​

Answer 1

Answer:

A number that can't be simplified to remove a square root (or cube root etc) is called surd .

There are six different types of surds, namely: Simple surds, Pure Surds, Similar Surds, Mixed Surds, Compound Surds, and Binomial Surds

Answer 2

• When we can't simplify a root under variable further or we can't remove the root sign that is called surd.It may be a square root or cube root or n th root .They are especially called irrational numbers.

Ex:-

$\\ \rm\longmapsto \sqrt{9}=3$Hence its not a surd.

but

.

$\\ \rm\longmapsto \sqrt{3},\sqrt{7}$Are surds.

There are six types of surds such as :

1. Simple surds
2. Pure Surds
3. Similar Surds
4. Mixed Surds
5. Compound Surds
6. Binomial Surds.
