Question

$(9 {x}^{3} + {y}^{2} z)( {x}^{3} {y}^{4} z)$
alguien me ayuda a resolverlo???​

Answer 1

Respuesta: =9x^6y^4z+x^3y^6z^2

Explicación paso a paso: \left(9x^3+y^2z\right)\left(x^3y^4z\right)

\mathrm{Poner\:los\:parentesis\:utilizando}:\quad \:a\left(b+c\right)=ab+ac

a=\left(x^3y^4z\right),\:b=9x^3,\:c=y^2z

=\left(x^3y^4z\right)\cdot \:9x^3+\left(x^3y^4z\right)y^2z

=9x^3\left(x^3y^4z\right)+y^2z\left(x^3y^4z\right)

\mathrm{Simplificar}\:9x^3\left(x^3y^4z\right)+y^2z\left(x^3y^4z\right):\quad 9x^6y^4z+x^3y^6z^2

=9x^6y^4z+x^3y^6z^2
