Question

Why do we need to rationalize the denominator?

Answer 1

To adjust the ques in easy form...we rationalise the denominator....

When ques is unable to solve and under root value comes in denominator then we rationalise it by using opposite sign..... Hope it helps uh

Answer 2

Hello Dear!!!

Here's your answer...

We rationalise the denominator to get a standard form.

If we rationalise the denominator,it will be easy to compute the value.

We divide and multiply the conjugate of the denominator with both numerator and denominator.

We can cancel the roots by multiplying with the conjugate of the denominator.This makes us easy to solve the problem.

So,we will rationalise the denominator.
