Question

1) -3x⁴y²-6x²y²+9x²y⁴2) -3 __a⁴ (2,1b²-0,7a+35) 7

Answer 1

Ответ:

1) = -3х^2y^2(x^2+2-3y^2)

2) = -2.1a^4(3b^2-a+50)

Answer 2

It seems like you have two expressions. Let's simplify them one by one:

1. -3x⁴y² - 6x²y² + 9x²y⁴

To simplify this expression, we can factor out common terms:

-3x²y²(x² - 2 - 3y²)

Now, we can't simplify this expression further without knowing specific values for x and y. If you have specific values for x and y, you can substitute them in to simplify further.

2. -3a⁴(2,1b² - 0,7a + 35) / 7

It appears that you have a fraction involving variables a and b. Let's simplify it:

-3a⁴(2.1b² - 0.7a + 35) / 7

Now, let's distribute the -3a⁴ into the expression inside the parentheses:

(-3a⁴ * 2.1b² + 3a⁵ * 0.7a - 3a⁴ * 35) / 7

Simplify each term:

-6.3a⁴b² + 2.1a⁶ - 105a⁴ / 7

Now, we can divide each term by 7 to further simplify:

(-6.3a⁴b² + 2.1a⁶ - 105a⁴) / 7

So, the simplified expression is:

-0.9a⁴b² + 0.3a⁶ - 15a⁴
