Answer 2

Oie, Td Bom?!

>>> Resolvendo as expressões.

a)

$(3x - 2) + (x - 4)$

$3x - 2 + x - 4$

$4x - 6$

b)

$(5x - 1) \: . \: (x + 3)$

$5x \: . \: (x + 3) - 1(x + 3)$

$5x {}^{2} + 15x - x - 3$

$5x {}^{2} + 14x - 3$

c)

$(2x {}^{3}y) {}^{4}$

$2 {}^{4} \: . \: (x {}^{3} ) {}^{4} \: . \: y {}^{4}$

$16x {}^{12} y {}^{4}$
