Swizzbeat Posted July 23, 2014 Share Posted July 23, 2014 Multiply both sides by 0. Link to comment Share on other sites More sharing options...
Arctic Posted July 23, 2014 Share Posted July 23, 2014 Multiply both sides by 0. You mean divide, he will get a kickass answer. 1 Link to comment Share on other sites More sharing options...
Mysteryy Posted July 23, 2014 Share Posted July 23, 2014 You mean divide, he will get a kickass answer. Some people just want to watch the world burn... xD 1 Link to comment Share on other sites More sharing options...
Cinnamon Posted July 23, 2014 Share Posted July 23, 2014 You can post in the Real-Life section. A homework section was already suggested but denied. Link to comment Share on other sites More sharing options...

RoomScape Posted July 23, 2014 Share Posted July 23, 2014 So what is your question? Sorry, I don't speak that language. Link to comment Share on other sites More sharing options...
Mysteryy Posted July 23, 2014 Share Posted July 23, 2014 (edited) So what is your question? Have you tried multiplying the top and bottom by the recipricol of the bottom? I am not sure how much knowledge you have, or if you know what that is. Also I am at work so its kind of hard for me to help out because I cant give you a ton of details. Try to multiply the top and bottom by (x-2)/(x-3) Doing this will probably give you some like terms, which you can then cancel out on the top and bottom, resulting in one of the answers. This is how you get (a fraction)/(a fraction) into a single fraction. Edited July 23, 2014 by Mysteryy 1 Link to comment Share on other sites More sharing options...
RoomScape Posted July 23, 2014 Share Posted July 23, 2014 C looks like a somewhat more complex answer compared to the others, plus C is just the default choice I go for, so I'd go with C. Link to comment Share on other sites More sharing options...

Arctic Posted July 23, 2014 Share Posted July 23, 2014 Oh. Just saw that what he said helped but here is a full working out with explanation. Question 8. Look at the explanation, otherwise my answers are useless and you won't learn. I didn't bother to multiple the factorials myself on paper but a calculator will verify it. 1 Link to comment Share on other sites More sharing options...

Mysteryy Posted July 23, 2014 Share Posted July 23, 2014 (edited) This helped me out, thanks and good luck in work. I have another set of questions if anyone else can help with: I am sorry I am at work so its hard to reply to your questions. For number 8 consider this: (n+1)! = n! * (n+1) now rewrite that expression as ((n!) * (n + 1) / n!) - n You can then cancel out the top n! with the bottom n! leaving us with: n + 1 - n from there its obvious that the answer is just 1 Ok now that I have time to answer your second question, a variable to a negative power is 1/variable^positive power eg: v^-2 = 1/(v^2) Using that you first add up all exponents, resulting in the condensed expression: r^(2+2/3) * t^(-1) = r^(8/3) * (1/t) = (r^(8/3)) / t If I am unclear or said something stupid I apoligize, I am standing up outside in 100 degree heat on a computer at work l0l It is quite difficult to make proofs in these conditions xD Edited July 23, 2014 by Mysteryy 2 Link to comment Share on other sites More sharing options...
