Explicação passo-a-passo:

[tex] \mathsf{ a^2-b^2=(a-b)\cdot(a+b)}[/tex]

[tex] \mathsf{ (2011)^2-(2010)^2}[/tex]

[tex] \mathsf{ (2011-2010)\cdot(2011+2010)}[/tex]

[tex] \mathsf{1\cdot4021 }[/tex]

4021

Resposta:

[tex](2011) {}^{2} - (2010) {}^{2} \\ (2011) {}^{2} - (2010) {}^{2} \\ (2011 - 2010) \times (2011 + 2010) \\ 1(2011 + 2010) \\ (2011 - 2010) \times (2011 + 2010) \\ 1 \times 4021 \\ 4021 \\ resposta \\ 4021[/tex]
