yes i did i think for me around 35-45 as raw score is coming....

Thanks! I was reading questions asked in subject test, I was good student during my class 12, I feelit wont be too difficult to crush the exam with great scores. Maximum scores I belive is 990. Right? Regards' Ankish

First of all, 16 factors as 2^4, so ALL the abelian groups of order 16 are: Z2 x Z2 x Z2 x Z2 Z4 x Z2 x Z2 Z4 x Z4 Z8 x Z2 Z16 The last two will have elements of order greater than 4, namely (1,1) in Z8 x Z2 which will be of order 8 and 1 in Z16 which is of order 16. In all the other groups, every nonzero element is of order 4 or 2 and so will satisfy x+x+x+x=0.

I don't know the exact answer to your question, but I did come across a post where the person got into Harvard and Princeton with 870/900 score. These were phd programs in statistics and operational research respectively.

what does R^R mean where where the R's are bold? what does R^R mean where where the R's are bold? Specifically I'm looking at the Princeton Review math subject test book, example 6.24 where it asks, "Is the ring R^R an integral domain?"

It is ok to post your question here. But I really want to mention, that according to the way you're writing your questions, there is little chance you will get the answer for them. You are extremely sloppy and careless about punctuation. You're putting as many dots as you want whenever you want. You're ignoring comas where they need to be put. You're inserting spaces before punctuation. ...

1. Just make equations. work/(5*p) = 60 work/(4*p) = ? Solving them gives 75.

Some problems from the rates section of Kaplan's book. I have not idea in how I can adreess these questions: 7. A marathon runner ran for two days. On the second day he ran 2 hours longer and at an average speed 1 mile per hout faster than he ran on the first day. If during the two days he ran a total of 64 miles and spent a total of ...
