Simplifying the Expression

To simplify the given expression, let's break it down step by step.

The expression is: (a + (3a + b))(2a - 5b) - 6(a - b)² - (-2a³b)³ × (-5a²b)²

Step 1: Simplify the expression within the first set of parentheses. - The expression within the first set of parentheses is (3a + b). - Multiplying this expression by (a + (3a + b)) gives us (a + (3a + b))(3a + b).

Step 2: Simplify the expression within the second set of parentheses. - The expression within the second set of parentheses is (2a - 5b).

Step 3: Simplify the expression within the third set of parentheses. - The expression within the third set of parentheses is (a - b)². - Squaring this expression gives us (a - b)(a - b).

Step 4: Simplify the expression within the fourth set of parentheses. - The expression within the fourth set of parentheses is (-2a³b)³ × (-5a²b)².

Now, let's simplify each part of the expression one by one.

Part 1: (a + (3a + b))(2a - 5b) - Distributing the terms, we get: - a(2a - 5b) + (3a + b)(2a - 5b) - Simplifying further, we have: - 2a² - 5ab + (6a² - 15ab + 2ab - 5b²) - Combining like terms, we get: - 8a² - 18ab - 5b²

Part 2: 6(a - b)² - Expanding the square, we have: - 6(a² - 2ab + b²) - Simplifying further, we get: - 6a² - 12ab + 6b²

Part 3: (-2a³b)³ × (-5a²b)² - Simplifying the exponents, we have: - (-2³a³b³) × (-5²a²b²) - Simplifying further, we get: - (-8a³b³) × (25a²b²) - Multiplying the coefficients and combining the variables, we have: - -200a^5b^5

Now, let's combine all the simplified parts of the expression:

(8a² - 18ab - 5b²) - (6a² - 12ab + 6b²) - (-200a^5b^5)

Simplifying further, we have:

8a² - 18ab - 5b² - 6a² + 12ab - 6b² + 200a^5b^5

Combining like terms, we get the simplified expression:

2a² - 6b² - 6a² + 200a^5b^5 - 6ab

Therefore, the simplified expression is:

-4a² - 6b² - 6ab + 200a^5b^5
