\(\left(\sqrt{2014}-\sqrt{2013}\right).\left(\sqrt{2014}+\sqrt{2013}\right)\)
=> \(\sqrt{2014^2}-\sqrt{2013^2}\)
=> \(2014-2013\)
\(=1\)
Vậy ..............
\(\left(\sqrt{2014}-\sqrt{2013}\right).\left(\sqrt{2014}+\sqrt{2013}\right)=1\)
\(VT=\left(\sqrt{2014}-\sqrt{2013}\right).\left(\sqrt{2014}+\sqrt{2013}\right)\)
\(=\sqrt{2014^2}-\sqrt{2013^2}\)
\(=2014-2013\)
\(=1=VP\left(dpcm\right)\)
Vậy....
