Probably pretty simple.

"Express as a single fraction with rational denominator"


\

a/b + c/d = (ad+bc) / (bd)

Solve it using that formula.

Dude this is easy.
1. You need to separate it into 2 different parts
2. rationlise it from there
3. add the 2 together

Sorry, I really need to see working.

Why can't you do it? Can you identify the problem that's preventing you from making progress?

Do you have an answer for it? The first question I mean

I can't Identify the problem preventing me, I just need to see working to compare and see what I'm doing wrong, sorry.

Have you learnt how to rationalise the denominator of a single fraction? If so, these questions are just based on that. Rationalise each denominator, and then add the fractions with rational denominators by taking a common denominator.

If you haven't yet learnt how to rationalise denominators, you probably should learn that first.

Dude this is a year 9/10 question. Did you get taught this is year 9/10 because if you didn't then your school didn't follow the maths curriculum properly

I'm sorry, but seriously this is irrelevant. All I asked for was working, yes I learnt surds and yes I was terrible at them hence my question.
