What is 9 squared?

Explanation:
To find 9 squared, you multiply 9 by itself. This calculation can be expressed as \(9 \times 9\). When you perform the multiplication, the result is 81. Therefore, 9 squared is equal to 81, which corresponds to the choice given. Squaring a number effectively means finding the area of a square with sides of that length. In this case, if you envision a square with each side measuring 9 units, the area would be calculated as \(9^2\), confirming that the area (or \(9^2\)) is indeed 81. Understanding squaring is fundamental in mathematics and helps in grasping more advanced concepts in algebra and geometry later on.
