Question

please explain Rationalisation of the denominator (the idea of conjugate) . as I do not understand it

Answer 1

Step-by-step explanation:

So basically, conjugate is a type of no. which converts the irrational no. into rational one.

Ex .. 5/root 2. is an irrational no.

Now if we multiply it by root 2 it would be rationalised...

5/root 2 × root 2 / root2 == 5root 2 / 2

Here root 2 is the conjugate...

Sorry but root 2 ka symbol is not available

If you don't understand I would answer again
