Many thanks for your help, I may be being a bit slow but how would I use the answer from the first equation to solve the second one?

I don't quite understand still even after I read the definition from the website you gave me.

But in #1, why isn't it a comic relief? Thanks.

The 2 before the sqrt50 just means 2 times sqrt50 Since sqrt50=5sqrt2 and sqrt8=2sqrt2 2*5sqrt2-2sqrt2 =10sqrt2-2sqrt2 =8sqrt2

but the other is telling a joke Still don't get it, sorry
