The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, .... In general, F_{k+2} = F_{k+1} + F_{k} . Here is some background info, we derive the following matrix for computing F_{100} : \mathbf{A} = \begin{bmatrix} 1 & 1 \\ 1 & 0 \end{bmatrix} \begin{bmatrix} F_{k+2} \\...

Hi, I have encountered some difficulties with the question in the zip file attached. Greatly appreciate any help given! Thanks in advance.

Line Segment Arithmetic Let all numbers be assigned an arbitrary collection of line segments equivalent in number to the number the line segments are assigned to: q = (q,q_) Let zero be assigned one arbitrary line segment. (0,_) 0 = (0,_) 1= (1,_) 2= (2,_,_) 3= (3,_,_,_) Let multiplication...

Hello, I ran in to this problem and I cant seem to show this although it seems intuitively correct: Given any positive integer $n>1$, prove that there are infinitely many integers $x$ satisfying $d(x)=n$. Where $d(n)$ is the number of positive divisors of $n$. I will appreciate the help.
