Hi, in my math textbook I have three question which the textbook does not teach you how to simplify please help. I don't just want the answer I want to know how to get the answer again if I receive a similar question.
These are the three questions. The correct answers are below each question question
131. (2^(n+2) + 12) / (5 * 2^n + 15)
132. (2^(2n+3) - (2n)^2) / 2^n
7 * (2^n)
133. (3^(n+1) + 9) / (3^(n-1) + 1)
Thanks in advance
