To simplify the expression (sqrt13+sqrt11)(sqrt13-sqrt11), we can use the difference of squares formula. The formula states that (a+b)(a-b) is equal to a^2 - b^2. Applying this formula to the given expression, we have (sqrt13)^2 - (sqrt11)^2, which simplifies to 13 - 11, resulting in 2. Therefore, the simplified expression is 2.
