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, let \( a = 2011 \) and \( b = 2010 \): - \( a - b = 2011 - 2010 = 1 \) - \( a + b = 2011 + 2010 = 4021 \) Now substituting these values into the formula: \[ 2011^2 - 2010^2 = (1)(4021) = 4021 \] So, \( 2011^2 - 2010^2 = 4021 \).
