## Description
<section id="description"> Considere o número 50. 502 = 2500 = 22 × 54, então φ (2500) = 2 × 4 × 53 = 8 × 53 = 23 × 53. 1 Então, 2500 é um quadrado e φ (2500) é um cubo. <p> Encontre a soma de todos os números n, 1 &lt;n &lt;1010 de modo que φ (n2) seja um cubo. </p><p> 1 φ denota a função totiente de Euler. </p></section>
