You can put this solution on YOUR website! if u is one how can i solve this euation: 3u^2
------
It's not an equation, there's no equal sign.
------
Even if it were, you already know what u is, no need to solve for it.
-----------------
All you can do with this is - Evaluate the EXPRESSION 3u^2 when u=1.
Substitute 1 for u
3u^2
= 3*1^1
= 3
