Solve the following equations leaving your answers in exact form - no decimal solutions. You should check your solutions work. (i) ln(x 1) + ln(x + 2) = ln(18) ex (ii) = 7e* - 12 ex Hint: Simplify the expression first. You may need to make the substitution m = = e in order to solve the equation. (iii) log (9) + log(3) = log (8)
