sqrt(4*x^2)*sqrt(13/52x^2 = x^2
\(\sqrt{4x^2}\times \sqrt{\frac{13}{52x^2} } =x^2\)
\(v=x^2\)
\(\sqrt{4v}\times \sqrt{\frac{13}{52v} } =v\)
\(4v\times \frac{13}{52v}=v^2\) [ * 52v
\(52v=52v^3 \)
\(v^2=1\)

\(\sqrt{4x^2}\times \sqrt{\frac{13}{52x^2} } =x^2\)
\(\sqrt {4(-1)^2}\times \sqrt{\frac{13}{52(-1)^2} } =(-1)^2\)
2 \(\times\) \(\frac{1}{2}\) \(= \ \ 1\)
\(\sqrt {4*1^2}\times \sqrt{\frac{13}{52*1^2} } =1^2\)
2 \(\times\) \(\frac{1}{2}\) \(= 1\)
