Question 29664: Hey guys! Almost out of Alg. II now (thank god)... Have a final coming up soon and I have most of the stuff we've covered over the term down.


However I have to cover these kinds of problems since these kind will be on the test. Teacher gave us 12 to do off a study guide worksheet as practice, I got some of them because of groups at school.


Sadly however I am having trouble with the following. If anyone can give me some insight on any of these listed (doesn't have to be all of them) as far as how to do each one (step by step preferrably) and how you came to the correct answer it would be of great help to me. I know these are more or less simple but I forgot how to do these ones with the multiplication, lots of terms, exponents /etc. I.E. the non-basic ones.


Thanks A bunch!


Oh and also there are a few im not 100% sure about that I did, please let me know if I got the answer right.
Oh and the one i wrote at m13/1 I noticed that it was actually 1/m13 so nevermind that one.

Answered a few. Sorry I cant read the rest.
The 9th question is wrong. You cannot cancel terms simply because they are common. You have to make sure that these terms are not being added or subtracted to other terms
for e.g
%282%2B2%2B3%29%2F%282%2B3%29
This DOES NOT equal 2
You have to first simplify( Add in this case) before you can cancel them
For the above question the correct answer is 7%2F5

Sorry about that! Should be able to read it just fine if you hold the mouse over the image the link sends you to for a few seconds, a box will pop up in lower bottom right corner of it. click it to zoom in, can see everything easily then.
Thanks a bunch for the help so far! Any more help is appreciated.
