To solve \(2011^2 - 2010^2\), we can use the difference of squares formula, which states that \(a^2 - b^2 = (a - b)(a + b)\). Here, we have \(a = 2011\) and \(b = 2010\). Calculating: \[ 2011^2 - 2010^2 = (2011 - 2010)(2011 + 2010) \] This simplifies to: \[ 1 \times (2011 + 2010) = 1 \times 4021 = 4021 \] So, \(2011^2 - 2010^2 = 4021\).
