A = 30.(1+5²+....+5⁶)

A = 6.5.(1+5²+....+5⁶) = 3.2.5.(1+5²+....+5⁶)

Vậy A chia hết cho 3;6;30

Dear Jenny.

Along time no see you. I so surprise when I get your email. You have a problem with your teeth, aren't you. According to me you should talk to your parents. And you should go to see the dentist. After this, you must eat less sugar and more vegetables.

Love you.

Angel.
