## Description
|
|
<section id="description"> Considere todas las combinaciones de números enteros de ab para 2 ≤ a ≤ 5 y 2 ≤ b ≤ 5: 22 = 4, 23 = 8, 24 = 16, 25 = 32 32 = 9, 33 = 27, 34 = 81, 35 = 243 42 = 16, 43 = 64, 44 = 256, 45 = 1024 52 = 25, 53 = 125, 54 = 625, 55 = 3125 Si luego se colocan en orden numérico, con cualquier repetición eliminada, obtenemos la siguiente secuencia de 15 términos distintos: 4, 8, 9, 16, 25, 27, 32, 64, 81, 125, 243, 256, 625, 1024, 3125 ¿Cuántos términos distintos hay en la secuencia generada por ab para 2 ≤ a ≤ n y 2 ≤ b ≤ n? </section>
