The expression x2y2 can be simplified by recognizing that it represents the product of two squared variables.
To simplify this, we can use the property of exponents which states that when multiplying like bases, we can add the exponents. For instance, x2 can be thought of as (xy)2, applying the same logic:
x2y2 = (xy)2
This means that the expression x2y2 simplifies into (xy)2, which is a more concise representation of the same relationship. So, the correct simplification is:
(xy)2
