Answer 1

Вот так наверное ты дашь только 10 баллов это мало слишком извини если я не права

Answer 2

Let's simplify each expression:

а) a¹ + 2a³ - 4a + 2a² - 3a²

Combining like terms:

a¹ + 2a³ - 4a + 2a² - 3a² = a + 2a³ + (2a² - 3a²) - 4a

Simplifying further:

a + 2a³ + (2a² - 3a²) - 4a = a + 2a³ - a² - 4a

The simplified expression is: 2a³ - a² - 3a

б) 1 + 2y - 4y³ - 6y + 4y³ - y⁵ - 9

Combining like terms:

1 + 2y - 4y³ - 6y + 4y³ - y⁵ - 9 = 1 + 2y - 6y - 6y + 4y³ + 4y³ - y⁵ - 9

Simplifying further:

1 + 2y - 6y - 6y + 4y³ + 4y³ - y⁵ - 9 = -8y + 8y³ - y⁵ - 8

The simplified expression is: -y⁵ + 8y³ - 8y - 8

в) 10x²y - 5xy² - 2x²y + x²y - 3xy²

Combining like terms:

10x²y - 5xy² - 2x²y + x²y - 3xy² = 10x²y - 2x²y + x²y - 5xy² - 3xy²

Simplifying further:

10x²y - 2x²y + x²y - 5xy² - 3xy² = (10x²y - 2x²y + x²y) - (5xy² + 3xy²)

The simplified expression is: 9x²y - 8xy²

г) 3ab³ + 6a²b² - ab³ - 2a²b² - 4a²b² + 7

Combining like terms:

3ab³ + 6a²b² - ab³ - 2a²b² - 4a²b² + 7 = (3ab³ - ab³) + (6a²b² - 2a²b² - 4a²b²) + 7

Simplifying further:

(3ab³ - ab³) + (6a²b² - 2a²b² - 4a²b²) + 7 = 2ab³ - 6a²b² + 7

The simplified expression is: 2ab³ - 6a²b² + 7
