Hi. I'll help with the first exercise. Please start new threads, if you would like help on other exercises.

3.(a)(i) Simplify: (√3 – √2) (2√3 + √2)

Please post what you tried, so we can check it. If you don't know how to begin, then we need to know whether you understand the distributive property.

Can you do the following multiplications?

(√3) (2√3 + √2) = ?

(-√2) (2√3 + √2) = ?

:)
