Question

me ayudan con resolución

Answer 1

Pasos:

13)  $8x^{2} y+16x^{2} y-10x^{2} y$

Sumar elementos similares: $8x^{2} y+16x^{2} y-10x^{2} y=14x^{2} y$

= $14x^{2} y$

14)  $17x^{4}y^{3}z^{2}+16x^{4}y^{3}z^{2}-28 x^{4}y^{3}z^{2}$

Sumar elementos similares: $17x^{4}y^{3}z^{2}+16x^{4}y^{3}z^{2}-28 x^{4}y^{3}z^{2}=5x^{4}y^{3}z^{2}$

= $5x^{4}y^{3}z^{2}$
