1. It seems like you meant to say "they are squared." This usually refers to squaring a number or an expression, which means multiplying it by itself. 2. For example, if you have a number $x$, then $x$ squared is written as $x^2$ and calculated as $x \times x$. 3. If you have a specific expression or number you want to square, please provide it, and I can help you with the calculation or explanation.
