Question

subtract:’y⁸z – zx⁷y⁷ – 6x⁷z⁵from z⁵x⁷– 2z⁷y⁸​

Answer 1

Answer:

$= {z}^{5} {x}^{7} - 2 {x}^{7} {y}^{8} - ( {y}^{8} z - z {x}^{7} {y}^{7 } - 6 {x}^{7} {z}^{5} ) \\ = {z}^{5} {x}^{7} - 2 {x}^{7} {y}^{8} - {y}^{8} z + z {x}^{7} {y}^{7 } + 6 {x}^{7} {z}^{5} ) \\ = 7{z}^{5} {x}^{7} - 2 {x}^{7} {y}^{8} - {y}^{8} z + z {x}^{7} {y}^{7 }$
