Question

2,8a⁴*(-3a³n) 6x⁴y-8y³+x⁴*5,4y+xy⁴-y³

Answer 1

Ответ:

1. -8,4а⁷n

2. 11,4x⁴y-9y³+xy⁴

Answer 2

To simplify the given expression, let's break it down into terms and combine like terms:

2 * 8a⁴ * (-3a³n) = -48a⁷n

6x⁴y - 8y³ + x⁴ * 5.4y + xy⁴ - y³ = 6x⁴y + x⁴ * 5.4y + xy⁴ - 8y³ - y³ = 6x⁴y + 5.4x⁴y + xy⁴ - 9y³

Therefore, the simplified expression is: -48a⁷n + 6x⁴y + 5.4x⁴y + xy⁴ - 9y³.
