Music, like the other fine arts, is what feeds the soul and touches the body, moving it. Anyone who has grown up with a musically talented parent knows the tremendous part that music plays in one's memory. And, anyone who has "been acquainted with the night" as Robert Frost put it, knows and can relate to the Blues.

Music can fit our moods, as well. I will always remember riding along with a friend years ago. This friend loved hard rock, but he had Johnny Cash's "Sunday Morning Coming Down" playing as I got into the car. "What is this?" I asked. "You don't ever listen to Country Western; in fact, you loathe it!"

"Yeah, it's the strangest thing: after breaking up with J____,it all seems to make sense now. Anyway, I think I feel like Johnny did in this song," he replied.

Yes, sometimes we are in harmony with what music says and it talks to us, and pulls at our hearts in most unusual ways, nurturing, comforting, commiserating, exhilirating, soothing, strengthening us against the dark. What would life be like without it? Terribly cold and silent, indeed.

A=3+3²+3³+...+3²⁰⁰⁹

=>3A=3²+3³+...+3²⁰¹⁰

=>3A-A=3²+3³+...+3²⁰¹⁰-(3+3²+3³+...+3²⁰⁰⁹)

=>2A=3²+3³+...+3²⁰¹⁰-3-3²-3³-...-3²⁰⁰⁹

=>2A=3³⁰¹⁰-3

=>2A+3=3²⁰¹⁰

mà 2A+3=3ⁿ
