Does anyone know how to turn root 18+10 over root 2 into the form a+b root 3?
Hope that makes sense.
(I know how to answer it as it’s quite easy but for some reason I cannot get it as root 3, I always get root 2 and I keep thinking there’s a typo in the maths paper)

I don't think that can be expressed in the form the form a+b root 3. A typo looks likely.
