Which is the biggest and which the smallest of these numbers?
2000^{2002} \quad\quad 2001^{2001}\quad\quad 2002^{2000}
How do they compare in magnitude?
Find S_r = 1^r + 2^r + 3^r + ... + n^r where r is any fixed positive integer in terms of S_1, S_2, ... S_{r-1}.
2\wedge 3\wedge 4 could be (2^3)^4 or 2^{(3^4)}. Does it make any difference? For both definitions, which is bigger: r\wedge r\wedge r\wedge r\dots where the powers of r go on for ever, or (r^r)^r, where r is \sqrt{2}?
