Simplify \(25-\frac{9}{4}\) to \(\frac{91}{4}\).
\[\frac{1}{2}\times 3\sqrt{\frac{91}{4}}\]
Simplify \(\sqrt{\frac{91}{4}}\) to \(\frac{\sqrt{91}}{\sqrt{4}}\).
\[\frac{1}{2}\times 3\times \frac{\sqrt{91}}{\sqrt{4}}\]
Since \(2\times 2=4\), the square root of \(4\) is \(2\).
\[\frac{1}{2}\times 3\times \frac{\sqrt{91}}{2}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[\frac{1\times 3\sqrt{91}}{2\times 2}\]
Simplify \(1\times 3\sqrt{91}\) to \(3\sqrt{91}\).
\[\frac{3\sqrt{91}}{2\times 2}\]
Simplify \(2\times 2\) to \(4\).
\[\frac{3\sqrt{91}}{4}\]
