 Question 5699: Thanks in advance- this fraction makes no sense to me. a^2m(b^m+1) / a^m(b) I know it looks confusing but to clarify, it reads: a to the second times m multiplied by b to the m plus one, divided by a to the m multiplied by b. *When I work it out I end up with a^2m-m(b^m). I have no real clue if I'm right. Click here to see answer by longjonsilver(2297)

 Question 5698: Hi, I actually have 2 questions relating to adding and subtracting fractions using variables. 1)x-y/x+y + x+y/x-y I thought it was 1 but now it seems that would be too easy. 2) 1/x - 1/x+4 = 1/3 *I know I'm supposed to find the LCD and multiply both sides by it, but I'm not sure what that is.
