Now I'm not 100% sure but I don't think there should be any equality sign. Especially clear in the second answer. The mark scheme implies the second one is valid for ln(0).

Is this from a past paper or textbook?

Q 4 and 5 on page 33 and the answer is on page 136

For the second one my AQA formula book says the Maclaurin's series for ln (1+x) is valid for . Assuming that is correct, as it's in the formula book, would my answer to the second one be correct or their ? Are my re-arrangements correct ?

For the first one it's just the simple (1+x)^n is valid for and am I right in thinking that has no equal sings ?

Sounds to me like you were right on both occasions.
