## Description
2018-10-10 20:20:40 +00:00
< section id = "description" > Considere el número 50. 502 = 2500 = 22 × 54, entonces φ (2500) = 2 × 4 × 53 = 8 × 53 = 23 × 53. 1 Entonces 2500 es un cuadrado y φ (2500) es un cubo. < p > Encuentre la suma de todos los números n, 1 < n < 1010 de manera que φ (n2) sea un cubo. < / p > < p > 1 φ denota la función totient de Euler. < / p > < / section >
