Web20 Oct 2010 · 1 Answer. Sorted by: 118. In general, one doesn't expand out log (a + b); you just deal with it as is. That said, there are occasionally circumstances where it makes sense to use the following identity: log (a + b) = log (a * (1 + b/a)) = log a + log (1 + b/a) (In fact, this identity is often used when implementing log in math libraries). Share. Web10 Aug 2024 · Using Set Theory Formula: n(A ∪ B) = n(A) + n(B) – n(A ∩ B) Wherein n(A ∩B) = n(A) + n(B) – n(A ∪B) = 20 + 28 – 36 = 48 – 36 = 12. Answer is 12. Q6: A survey was conducted in a class of 100 children and it was found out that 45 of them like Maths whereas only 35 like Science. 10 students like both subjects. Using set theory ...
