Preciso pra hj, ajudem pfvr

Answer 1

Resposta:

d) $6x^8$

e) $-8x^5y^{12}$

f) $-3a^4b^4$

Explicação passo a passo:

d) $2x^2\cdot \:3x^5x^1$

$=6x^2x^5x^1$

$=6x^{2+5+1}$

$=6x^8$

e) $2xy^5\left(-4xy\right)x^3y^6$

$=-2xy^5\cdot \:4xyx^3y^6$

$=-8xy^5xyx^3y^6$

$=-8x^2y^5yx^3y^6$

$=-8x^5y^5yy^6$

$=-8x^5y^{12}$

f) $abab\cdot \:3ab\left(-ab\right)$

$=-abab\cdot \:3abab$

$=-bb\cdot \:3ba^{1+1+1+1}b$

$=-bb\cdot \:3ba^4b$

$=-3a^4b^{1+1+1+1}$

$=-3a^4b^4$
