# Rationalise Surds Watch

1. Alright, so I've got the OCR Maths paper in like 2 days so I'm going over questions I struggled on in the Mock.

3 + √2 / √2

- So, I think I know how to do it but honestly all the solutions online seem to be with different styles of questions, anyone help?

I start by multiplying by one, giving:
3√2 + 2 / 2

/ represents divide or over
Is this what the examiner would want?
I'm thinking maybe I need to cancel the 2 out somehow?

Cheers.
