It seems you're referring to the notation where "10" has a small number (or "superscript") above it. In mathematical notation, this could imply exponentiation.
If "10 with a small 2 on top" (which can be written as \(10^2\)) indicates 10 raised to the power of 2, then:
\[ 10^2 = 10 \times 10 = 100 \]
If "10 with a small tree on top" is referring to a number like 3 (assuming "tree" is a typographical error or a playful way to refer to the number), then "10 with a small 3 on top" (which would be \(10^3\)) would yield:
\[ 10^3 = 10 \times 10 \times 10 = 1000 \]
So, to clarify:
- \(10^2\) (10 with a small 2) equals 100.
- \(10^3\) (10 with a small 3) equals 1000.
If you meant something different, please provide additional context!
