Answer 2

Ответ:

27а^3-8b^3-27a^3+12ab^2=12ab^2-8b^3

Answer 3

To simplify the expression 27a³-8b³-3a(9a²-4b²), let's break it down step by step:

1. Distribute the -3a to the terms inside the parentheses: -3a(9a²-4b²) = -3a * 9a² + -3a * -4b²

   This gives us: -27a³ + 12ab²

2. Now, let's combine the simplified expression with the other terms: 27a³ - 8b³ - 27a³ + 12ab²

   Since we have -27a³ and 27a³, they cancel each other out, leaving us with: -8b³ + 12ab²

Therefore, the simplified form of the expression 27a³-8b³-3a(9a²-4b²) is -8b³ + 12ab².
