Пояснение.
Решение.
\[\textbf{а)}\ \left( \sqrt{7} \right)^{2} = 7\]
\[\textbf{б)}\ \left( - \sqrt{26} \right)^{2} = 26\]
\[\textbf{в)} - 2\sqrt{14} \cdot \sqrt{14} = - 2 \cdot 14 =\]
\[= - 28\]
\[\textbf{г)}\ \left( 3\sqrt{5} \right)^{2} = 9 \cdot 5 = 45\]
\[\textbf{д)}\ 0,5 \cdot \left( - \sqrt{8} \right)^{2} = 0,5 \cdot 8 = 4\]
\[\textbf{е)}\ \left( - 2\sqrt{15} \right)^{2} = 4 \cdot 15 = 60\]
\[\textbf{ж)}\ \left( \frac{\sqrt{3}}{2} \right)^{2} = \frac{3}{4} = 0,75\]
\[\textbf{з)}\ \left( \frac{\sqrt{3}}{\sqrt{6}} \right)^{2} = \left( \sqrt{\frac{3}{6}} \right)^{2} = \frac{3}{6} = \frac{1}{2} =\]
\[= 0,5\]
