Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[FINDs{e}^{2}v{n}^{2}ra{t}^{2}{\imath }^{2}os-\frac{1}{3}AND\times \frac{2}{7}\]
Use Square Rule: \({i}^{2}=-1\).
\[FINDs{e}^{2}v{n}^{2}ra{t}^{2}\times -1\times os-\frac{1}{3}AND\times \frac{2}{7}\]
Simplify \(FINDs{e}^{2}v{n}^{2}ra{t}^{2}\times -1\times os\) to \(FINDs{e}^{2}v{n}^{2}ra{t}^{2}\times -os\).
\[FINDs{e}^{2}v{n}^{2}ra{t}^{2}\times -os-\frac{1}{3}AND\times \frac{2}{7}\]
Regroup terms.
\[-FINDs{e}^{2}v{n}^{2}ra{t}^{2}os-\frac{1}{3}AND\times \frac{2}{7}\]
Use this rule: \(\frac{a}{b} \times \frac{c}{d}=\frac{ac}{bd}\).
\[-FINDs{e}^{2}v{n}^{2}ra{t}^{2}os-\frac{1\times AND\times 2}{3\times 7}\]
Simplify \(1\times AND\times 2\) to \(2AND\).
\[-FINDs{e}^{2}v{n}^{2}ra{t}^{2}os-\frac{2AND}{3\times 7}\]
Simplify \(3\times 7\) to \(21\).
\[-FINDs{e}^{2}v{n}^{2}ra{t}^{2}os-\frac{2AND}{21}\]
-FINDs*e^2*v*n^2*r*a*t^2*o*s-(2*AND)/21
