Hello allI am currently re learning a specific maths syllabus as it's been a good decade since I last went over it. Part of it is surds. I'm working through some practise questions and one I'm stuck on is to simplify the following:-4 root 5 x 3 root 11Apologies for not using the root symbol but after reading the tutorial on tex I still have no idea how it works.Anyway, my problem with the above question is I can see anyway to simplify root 5 and root 11 any further.Can someone point me in the right direction?Kind regardsAnthony
