Penjelasan dengan langkah-langkah:

$frac{ {( {x}^{n - 1} {y}^{n} ) }^{3} }{ {x}^{2n} {y}^{6 + n} }$

$= frac{ {x}^{3n - 3} {y}^{3n} }{ {x}^{2n} {y}^{6 + n} }$

$= frac{ cancel{ {x}^{3n - 3}} {y}^{ cancel{3n}} }{ cancel{ {x}^{2n}} cancel{{y}^{6 + n} } }$

$= {x}^{n - 3} {y}^{2n - 6}$

$a = n - 3 : : \ b = 2n - 6$

$frac{a}{b} = frac{n - 3}{2n - 6}$
