    Question about simplifying congruences

    Is it because 25|250 and 25|150 so the remainder is 65t+5?

    Question about simplifying congruences

    That means 25|125, sorry I guess the variables just confuses me.

    Question about simplifying congruences

    Homework Statement I am looking at an example from my book and I have no clue how this is done.Homework Equations I solved the left hand side and got this 125t3+75t2+50t+4 How did they reduce it to 65t+5?The Attempt at a Solution http://i48.tinypic.com/2v2gpap.jpg

    What is instance characteristics in performance alalysis?

    I am studying performance analysis and character instance gets brought up a lot. I am unclear to what this means. It also talks about functions of instance characteristics. Can someone elaborate?

    Feeling unmotivated, any advice?

    I am a jr cs student. I just transferred to a university from a community college and I feel a HUGE different in terms of difficulty. I have been working on 1 assignment day and night and I can't seem to get it done. The assignment is much larger than I am used to and I am getting bugs from...

    Proving inequality with mathematical induction

    I think I got it. So, 5k+1 +9 < 6(5k+9) 5*5k + 9 < 6*5k + 54 5*5k < 6 * 5k since 5 < 6 5*5k + 9 < 6 * 5k + 54 since 9<54 Does this look right?

    Proving inequality with mathematical induction

    I am having trouble proving these. I cannot figure out how to get to the conclusion. Here is my attempt. The stuff in red is just side work and is not part of the proof. I always get stuck on these types of problems, can someone offer some tips on how to approach these kind of problems in...

    Understanding Divisibility Rules: Proving 4 Does Not Divide n^2 + 5

    I like the way you did the first two proofs, they look simple and to the point. I understand that there are many ways to do the same proof and it is always better to be able to write proofs efficiently because not all proofs are always this short. I am reluctant to use your mod proof because...

    But there is nothing wrong with my proof right?

    Understanding Divisibility Rules: Proving 4 Does Not Divide n^2 + 5

    Prove: For all integer n, 4 does NOT divide n2 + 5 The definition of | means the definition of divide. I need very thorough correction, down to the last support for every thing. Thank you

    Mod or quotient remainder theorem (QRT)

    My approach is correct, since I got the correct answer. I'm not quite sure what you are doing with the subscripts

    Mod or quotient remainder theorem (QRT)

    You mean n mod 5 = 3? I am only asking because my teacher is very strict about this stuff, he requires us to state all definitions used. But I think saying the definition of MOD would make more sense because QRT is kinda implied in def of MOD
