\(\sqrt{\left(1-\sqrt{2012}\right)^2}\sqrt{2013+2\sqrt{2012}}\)
\(=\sqrt{\left(1-2\sqrt{503}\right)^2}\sqrt{\left(1+\sqrt{2012}\right)^2}\)
\(=\left(2\sqrt{503}-1\right)\left(1+\sqrt{2012}\right)\)
\(=\left(2\sqrt{503}-1\right)\left(1+2\sqrt{503}\right)\)
\(=\left(2\sqrt{503}-1\right)\left(2\sqrt{503}+1\right)\)
\(=4\cdot503-1\)
\(=2012-1\)
\(=2011\)
