Пояснение.
Решение.
\[\left( \sqrt{25} \right)^{2} = 25\]
\[\left( \sqrt{81} \right)^{2} = 81\]
\[\left( \sqrt{2} \right)^{2} = 2\]
\[\left( \sqrt{3} \right)^{2} = 3\]
\[\left( - \sqrt{4} \right)^{2} = 4\]
\[\left( \sqrt{5} \right)^{2} = 5\]
\[\left( - \sqrt{6} \right)^{2} = 6\]
\[\left( \sqrt{\frac{1}{2}} \right)^{2} = \frac{1}{2}\]
\[\left( \sqrt{1,3} \right)^{2} = 1,3\]
