Question

(7x^2y^3z^4)(x^4y^3z)

Answer 1

$(7x^2y^3z^4)(x^4y^3z)$

$\mathrm{Quitar\:los\:parentesis}:\quad \left(a\right)=a$

$=7x^2y^3z^4x^4y^3z$

$\mathrm{Aplicar\:las\:leyes\:de\:los\:exponentes}:\quad \:a^b\cdot \:a^c=a^{b+c}$

$x^4x^2=\:x^{2+4}=\:x^6$

$y^3y^3=\:y^{3+3}=\:y^6$

$z^4z=\:z^{4+1}=\:z^5$

$=7x^6y^6z^5$
