Maths, rationalising Surds

https://pmt.physicsandmathstutor.com/download/Maths/A-level/C1/Worksheets-Notes/Edexcel%20C1%20Revision%20Sheet.pdf

C1, key points question 1.
Rationalize 1/Suqareroot A multiply by Squaretoot A/Squareroot A.

I keep getting squareroot A/ A

Can someone just give me the answers cuz I don't trust myself? I haven't done maths in so long. Literally forgot everything

Rationalizing means removing the surd from the denominator.
Your answer of 'squareroot A / A' is correct because the denominator is no longer a surd. It's perfectly fine to leave the numerator in surd form :smile:

Oh, so that's what it means. Forgot about that so I just started doing what seemed to make sense.
