Best ResponseYou've already chosen the best response.0The mathematical language allows very little room for typos. Could you check if there's any typo in the question? Example: is it i) 2a^2 => 2a + 2, or is it i) 2a+2 => 2(a+2) ? etc. All exponents must be preceded by ^, and parentheses cannot be omitted. Does A (in (ii) ) mean the same thing as a?
