This one's so easy that even I could do it:
I've been told by the best minds that math is racist, so that's all the more reason to keep practicing it, right? Anyway, my answer will be in the comments.

We're given:
9^999 + 9^999 + 9^999 = ?
This can be rewritten as:
3(9^999)
In the exponential expression, the base 9 can be rewritten as 3^2, which means the expression inside the parentheses can be rewritten as
3^1998
power rule: (a^m)^n = a^mn
The full expression, then, is:
3(3^1998)
3 is basically 3^1, so add powers because the other power rule is
a^m • a^n = a^(m+n)
So the answer is
3^1999.
QED.
