To solve \(2011^2 - 2010^2\), you can use the difference of squares formula, which states that \(a^2 - b^2 = (a-b)(a+b)\). Here, \(a = 2011\) and \(b = 2010\). So, we have: \[ 2011^2 - 2010^2 = (2011 - 2010)(2011 + 2010) \] Calculating each part: \[ 2011 - 2010 = 1 \] \[ 2011 + 2010 = 4021 \] Now, substituting back into the equation: \[ 2011^2 - 2010^2 = 1 \cdot 4021 = 4021 \] Therefore, the answer is \(4021\).
