Question

multiplicacion de monomios:
$( - \frac {3}{5} a {}^{2}b)( \frac{10}{27} ab {}^{2} )$
​

Answer 1

$( - \frac {3}{5} a {}^{2}b)( \frac{10}{27} ab {}^{2} )$

$( - \frac {3}{5} a {}^{2}b)( \frac{10}{27} ab {}^{2} ) \\ \\ - 3 a {}^{2}b \times \frac{2}{27} ab {}^{2} \\ \\ - a {}^{2} b \times \frac{2}{9} ab {}^{2} \\ \\ - \frac{2}{9} a {}^{3} b {}^{3}$

R/= $- \frac{2}{9} a {}^{3} b {}^{3}$
