Answer 2

1. Let's simplify the expression 3x(x-8) - 6(x²-2x) step by step:

First, we distribute the terms inside the parentheses: 3x(x-8) - 6(x²-2x) = 3x * x - 3x * 8 - 6x² + 6 * 2x

Simplifying further: = 3x² - 24x - 6x² + 12x

Now, we combine like terms: = (3x² - 6x²) + (-24x + 12x) = -3x² - 12x

So, the simplified expression is -3x² - 12x.

2. Let's simplify the expression -4m³n⁵ × 5n²m⁴ step by step:

First, we multiply the coefficients: -4 × 5 = -20

Next, we multiply the variables with the same base, m and n, and add their exponents: m³ × m⁴ = m^(3+4) = m⁷ n⁵ × n² = n^(5+2) = n⁷

Combining these results, we get: -20m⁷n⁷

So, the simplified expression is -20m⁷n⁷.
