You can get this fast by knowing that 9 squared is 81. This is the only answer that ends with one.

To square a number, all you have to do is multiply it by itself.
39 squared is 39x39.
You really should know how to multiply numbers together on paper, but if you're asking Yahoo! Answers for the answer anyway, you may as well find an online calculator and use that.

D: 1,521
I didn't even have to do the multiplication.
Since 9 times 9 is 81, that means the number must end in 1.

Just type 39^2 onto Google. ^2 is the internet way of writing squared.
