Question

(5а²+10а)-(а²-1+8а)а6⁴-3а²(3а²+а)ну(х-у)+2ху(х+у)(1-у)*0,2х²у-(2ху-х)*ху​

Answer 1

Первое =25а+10а-2а+1-8а=25а+1

Второе 1296а-81а-9а=1206а. Третье и четвертое не знаю

Answer 2

It seems like you've provided a mathematical expression with variables (a, x, y) and various operations. Let's break it down step by step and simplify the expression:

Given expression: $(5a^2 + 10a) - (a^2 - 1 + 8a)a^6 - 3a^2(3a^2 + a)ny(x - y) + 2xy(x + y)(1 - y) \times 0.2x^2y - (2xy - x)xy$

First, let's simplify each term step by step:

1. $(5a^2 + 10a)$

2. $(a^2 - 1 + 8a)a^6$ Expand: $a^8 - a^6 + 8a^7$

3. $3a^2(3a^2 + a)$ Expand: $9a^4 + 3a^3$

4. $ny(x - y)$ This term is a bit ambiguous as it's not clear what "ny" represents. Please clarify or provide more information.

5. $2xy(x + y)(1 - y) \times 0.2x^2y$ Expand: $0.4x^3y^2(1 - y)(x + y)$

6. $(2xy - x)xy$ Expand: $2x^2y^2 - x^2y$

Now, let's combine all the simplified terms based on the operations provided in the original expression:

$(5a^2 + 10a) - (a^8 - a^6 + 8a^7) - (9a^4 + 3a^3)ny(x - y) + 0.4x^3y^2(1 - y)(x + y) - (2x^2y^2 - x^2y)$

Without further information or clarification for the "ny" term, we can't simplify the expression any further. If you can provide more context or clarify the "ny" term, I'd be happy to help simplify the entire expression.
