\(\sqrt{\frac{7}{5}} - \sqrt{\frac{5}{7}} = x\)
\(x^2 = \frac{7}{5} - 2\sqrt{1} + \frac{5}{7}\)
\(x^2 = \frac{74}{35} - 2\)
\(x^2 = \frac{4}{35}\)
\(x = \frac{2}{\sqrt{35}}\)
Answer A.
\(x^2 = \frac{7}{5} - 2\sqrt{1} + \frac{5}{7}\)
\(x^2 = \frac{74}{35} - 2\)
\(x^2 = \frac{4}{35}\)
\(x = \frac{2}{\sqrt{35}}\)
Answer A.
