Question

Me ajudem presciso disso !!!!

Answer 1

$5) \\ \\ -7a x^2 , -1,8a^3x \\ \\ \\ (-7ax^2) * (-1,8a^3x) \\ \\ \\ => 12,6a^5x$

====
$6) \\ \\ (2ax) * (-1,25ax^2) * (-a^2x ) \\ \\ (2ax)(1,25a^2 * ax^2) \\ \\ => 2,5a^3x^2 * ax^2$

====
$7) \\ \\(-a) * (-m) * (-m^3) * (-a) \\ \\ \\(-a) * (-m) * (m^3a) \\ \\ (-a) * (-m^4a) \\ \\ => m^4a^2$
