OMG, thank you very much, I am just about to finish a bachelor's degree in Software Engineering and looking to continue my studies abroad (I was firstly thinking about the US, but the processes and eligibility requirements are such a pain in the but, so I decided to go to the UK, where it is...

In the natural numbers, N, find the lowest such that half of it is a perfect square, one-third is a perfect cube, and one fifth is a perfect fifth power. thats the assignment

ohhh! i knew it had something to do with those numbers being simple. Ok, it's Euclids algorithm (which i said myself d'uh) ... so the number a can be factorized by simple numbers (2, 3 and 5 in this case) ... but how do I find their powers? and just to make sure, in here 2a this "a" here is...

Yessss! that's exactly what I am asking! :) Thank you, my math-english is so bad, I am really having troubles setting the words right. not much :) i can see that 2|a, 3|a, 5|a .. but i can't go passed that... i tried doing a more equations with the given statements, but i seem to be going in...

Yeah, well, I tried ... the Latex reference was not displaying the equations right, that's why i did it in Word and uploaded an image. I am sorry if that put u into trouble, but the code was not working right, all it gave me in the preview was a few red lines. So again, I am sorry. Yes, I might...

Homework Statement Find the lowest number n from N that satisfies: Homework Equations http://img72.imageshack.us/my.php?image=zadacaqw8.jpg Please see attached if k is any number from N The Attempt at a Solution I have absolutely no idea where to start. :(

Homework Statement prove by mathematical induction that it is true: \frac{1}{2}+\frac{1}{2^{2}}+\frac{1}{2^{3}}+...+\frac{1}{2^{n}} < 1
