Answer:
[tex](15)(x^{8})(y^{5})(z^{7})[/tex]
Step-by-step explanation:
we have
[tex](5x^{4}y^{2}z^{2})(3x^{4}y^{3}z^{5})[/tex]
Group terms that contain the same variable
[tex](5x^{4}y^{2}z^{2})(3x^{4}y^{3}z^{5})=(5*3)(x^{4}x^{4})(y^{2}y^{3})(z^{2}z^{5})[/tex]
[tex]=(15)(x^{4+4})(y^{2+3})(z^{2+5})[/tex]
[tex]=(15)(x^{8})(y^{5})(z^{7})[/tex]
