alg_sum_ap_v1_1419126231_215
A digital clock logs events every second, assigning each a sequential number starting from 1. During a test lasting $\sum_{k=0}^{683} (2k + 100)$ seconds, engineers monitor how many logged event numbers $j$ satisfy both $j \leq \sum_{k_1=0}^{12} (2k_1 + 601)$ and $j^4 \leq 4032880071611521$. The system reports the tota...

A rectangular garden has area $1587600$ square meters, with integer side lengths. The smallest possible perimeter corresponds to sides $x_1$ and $y$ minimizing $x_1 + y$. This minimum sum is used as a constant in the quartic equation $x^4 - 30x^3 + 327x^2 - 1522x + (x_1 + y) = 0$. Let $M$ be the sum of all positive rea...
