# Rationalisation problem. watch

1. 1/sqrt(2) (2sqrt(2)-1) +sqrt(2) (1-sqrt(8)

I've got so far as:

sqrt(2)/ (2sqrt(2)-1) + sqrt(2) (1-sqrt (sqrt(2)*2).

cheers.
2. Do you think you could make it more clear what you are trying to express. Use latex or something.
3. sqrt(2)/-1)(sqrt(2)*2). + sqrt(2) (1-sqrt (2sqrt(2)

have you tried this?
4. KH, think that will do the trick
