    I haven't done surds in a while and almost finished answering this question but I was wondering if 7root3 + 3 would equal 10root3? Sorry if this sounds like a stupid question it's just I haven't done surds in a while.

    7root3 +3root3=10root3 not 7root3+3 and if you are having any difficulties then substitute x=root3 7x+3x=10x=10root3
