Simplify \(x\times 3.5\times 3.5\times 3.5\times 4\) to \((171.5)x\).
\[171.5x=14\times 14\times 21\]
Simplify \(14\times 14\) to \(196\).
\[171.5x=196\times 21\]
Simplify \(196\times 21\) to \(4116\).
\[171.5x=4116\]
Divide both sides by \(171.5\).
\[x=\frac{4116}{171.5}\]
Simplify \(\frac{4116}{171.5}\) to \(24\).
\[x=24\]
x=24
