Para resolver \( 2011^2 - 2010^2 \), podemos usar a diferença de quadrados, que é expressa pela fórmula: \[ a^2 - b^2 = (a - b)(a + b) \] Aqui, \( a = 2011 \) e \( b = 2010 \). Ao aplicar a fórmula, temos: \[ 2011^2 - 2010^2 = (2011 - 2010)(2011 + 2010) = 1 \times 4021 = 4021 \] Portanto, o resultado é \( 4021 \).
