Answer 1

Вот ответ надеюсь правильно

Answer 2

Let's simplify each expression step by step:

1. Simplifying (-a^3)^2: Applying the exponent rule, we have: (-a^3)^2 = (-1)^2 * (a^3)^2 = 1 * a^(3*2) = a^6

   Therefore, (-a^3)^2 simplifies to a^6.

2. Simplifying ab(-5ab^2)×(4a^2b): We can simplify this expression by multiplying the coefficients and combining the variables with the same base. (-5ab^2) × (4a^2b) = -5 * 4 * a * a^2 * b * b^2 = -20a^(1+2) * b^(1+2) = -20a^3 * b^3

   Therefore, ab(-5ab^2) × (4a^2b) simplifies to -20a^3 * b^3.
