8. CBQ - Concept of rationalism

Varun learned about rationalizing the denominator while solving problems with surds. He saw that fractions with square roots in the denominator can be converted into simpler forms.

 1. The rationalization of $\frac{1}{\sqrt{2}}$ gives:

 

2. The rationalizing factor of  $\frac{1}{\sqrt{3}+1}$ is:

 

3. If \(a\) $\ne$ \(0\) is a rational number and \(b\) is an irrational number, then the product \(a\)\(b\) is:

 

4. The denominator of a rationalized fraction should:
