4^(3-1) + 8 = 24
...I don't know if I can use powers, but I'm not coming up with a solution right now.

Edit: 4(3+1) + 8

5 squared

The number of strokes it takes to write thirteen x's is 26. (when not in script)

uhm... 27

When you write the letter "x" you first write a \ then a /. That's two strokes. So if you want 28 strokes, you make fourteen x's, is what I meant by the x's.

yep, i knew that.

doesn't work the same way with 29. =)
