Você consegue resolver esse desafio sem usar papel? Temos o sistema: A² = 50 e AB = 100. O objetivo é descobrir quanto vale B². Esse tipo de problema parece difícil à primeira vista, mas fica simples quando usamos propriedades matemáticas fundamentais das potências. Sabemos que A² = 50. Também sabemos que AB = 100. Se elevarmos a expressão AB ao quadrado, obtemos (AB)² = A²B². Como AB = 100, então (AB)² = 100² = 10000. Mas (AB)² também pode ser escrito como A² · B². Substituindo o valor conheci
