Answer 1

Oie, Td Bom?!

A)

$= - 11x {}^{2} \: . \: 2x {}^{5} y {}^{6} \: . \: xy {}^{3} \\ = - 22x {}^{2 + 5} y {}^{6 + 3} x \\ = - 22 x{}^{7} y {}^{9} x \\ = - 22x {}^{7} y {}^{6} x {}^{1} \\ = - 22x {}^{7 + 1} y {}^{9} \\ = - 22x {}^{8} y {}^{9}$

B)

$= ( - 4x {}^{3} m {}^{2} b {}^{4} ) {}^{3} \\ = ( - 4b {}^{4} m {}^{2} x {}^{3} ) {}^{3} \\ = ( - 4) {}^{3} \: . \: (b {}^{4} ) {}^{3} \: . \: (m {}^{2} ) {}^{3} \: . \: (x {}^{3} ) {}^{3} \\ = - 64b {}^{12} m {}^{6} x {}^{9}$
