Answer #1
Olá! Para fazer, você precisa estar atento aos tipos de conjuntos. Se os elementos vão pertencer aos N,Z,R…enfim:
*A=H (pois x assume valores acima de 1, infinitos.)
*G=d (pois x assume valores 2 e/ou 3, já que contemplam as raízes da equação.)
*B=J (pois x assume valor em que, a raiz de 49 pode ser -7 ou 7,B, e o J)
*C=F (em que x do conj.C é o vazio, pois é um conj. natural, e não inteiro.)
*E=I (pois x de E será 2,3,7; divisores primos de 84.)
Espero ter ajudado. Exercite, e bons estudos!
