Question

f)(+2ky^6b^3). (-ky^3b). (-5ky^3b) efetue as multiplicações de monômios

Answer 1

Oie, Td Bom?!

$= (2ky {}^{6} b {}^{3} ) \: . \: ( - ky {}^{3} b) \: . \: ( - 5ky {}^{3} b)$

$= (2b {}^{3} ky {}^{6} ) \: . \: ( - bky {}^{3} ) \: . \: ( - 5bky {}^{3} )$

$= 2b {}^{3} ky {}^{6} bky {}^{3} \: . \: 5bky {}^{3}$

$= 10b {}^{3} ky {}^{6} bky {}^{3} bky {}^{3}$

$= 10b {}^{3} k {}^{1} y {}^{6 + 3 + 3} b {}^{1} k {}^{1} b {}^{1} k {}^{1}$

$= 10b {}^{3 + 1 + 1} k {}^{1 + 1 + 1} y {}^{12}$

$= 10b {}^{5} k {}^{3} y {}^{12}$
