Answer:

$\frac{3 {x}^{2} }{2y {}^{4} }$

Step-by-step explanation:

$\frac{21x {}^{6}y {}^{5} }{14 {x}^{2} y {}^{9} }$

<h3>i) divide the numbers</h3>

$( \frac{21}{14})( \frac{x {}^{6} y {}^{5} }{ {x}^{2}y {}^{9} })$

$( \frac{3}{2} )( \frac{x {}^{6} y {}^{5} }{ {x}^{2}y {}^{9} })$

<h3>ii) simplify the like terms with the same base by substracting their exponents</h3>

$( \frac{3}{2} )(x {}^{6 - 2} y {}^{5 - 9} )$

$( \frac{3}{2} )(x {}^{4} y {}^{ - 4} )$

$\frac{3x {}^{2} }{2y {}^{4} }$
