Take out the constants.
\[(457\times 72)dddvo\imath \imath \imath \]
Simplify \(457\times 72\) to \(32904\).
\[32904dddvo\imath \imath \imath \]
Simplify.
\[32904{d}^{3}vo\imath \imath \imath \]
Use Product Rule: \({x}^{a}{x}^{b}={x}^{a+b}\).
\[32904{d}^{3}vo{\imath }^{3}\]
Isolate \({\imath }^{2}\).
\[32904{d}^{3}vo{\imath }^{2}\imath \]
Use Square Rule: \({i}^{2}=-1\).
\[32904{d}^{3}vo\times -1\times \imath \]
Simplify.
\[-32904{d}^{3}vo\imath \]
Regroup terms.
\[-32904\imath {d}^{3}vo\]
