What is the result of the expression (2+3)²?

To find the result of the expression (2+3)², start by simplifying the expression inside the parentheses. The sum of 2 and 3 is 5, so we rewrite the expression as 5². Now, calculating 5² involves multiplying 5 by itself, which equals 25. Therefore, the correct result of the expression (2+3)² is indeed 25. This demonstrates the importance of following the order of operations, which dictates that calculations within parentheses are performed first, followed by exponentiation.
