Step 1: Understanding the Concept:
In MS-Excel, formulas and functions are used to perform calculations.
The square of a number is obtained by multiplying the number by itself.
Step 2: Key Formula or Approach:
If a number is in cell X2, the square is \(X2 \times X2\).
In Excel, this is written as \(=X2*X2\) or \(=X2^2\).
However, the options are just simple expressions.
Option (A) X2 could be interpreted as "X squared" in some contexts.
But the standard Excel formula is \(=X2^2\) or \(=X2*X2\).
The options are not in proper Excel formula format.
Among the given options, X2 is the only one that represents a cell reference.
The question might be testing if you know that X2 is a cell reference.
So, the correct option is (A).
Step 3: Final Answer:
Therefore, option (A) is correct.
