$= -5 a^(4)b^(5)$

$(45 a^11b^13) / (-9 a^7b^8)$

$= (45 / -9) * ( a^11b^13) / ( a^7b^8)$

$= (cancel45 / cancel(-9)) * color(blue)(( a^11b^13) / ( a^7b^8)$

$= (-5) * color(blue)( ( a^11b^13) / ( a^7b^8)$

$= (-5) * color(blue)( a^((11 - 7)) * b^((13 - 8))$

$= (-5) * color(blue)( a^(4) * b^(5)$

$= -5 a^(4)b^(5)$
