Answer 2

Давайте упростим данные выражения:

а) -3xy * 2xy²: Умножим коэффициенты (-3) и (2), получаем -6. Умножим переменные x и x², получаем x^(1+2) = x³. Таким образом, -3xy * 2xy² = -6x³y².

б) (-2a²b)³: Возводим каждый элемент внутри скобок в куб: (-2a²b)³ = (-2)³ * (a²)³ * (b)³ = -8a^6b³.

в) (-x³у²)⁴: Возводим каждый элемент внутри скобок в четвертую степень: (-x³у²)⁴ = (-x)⁴ * (у²)⁴ = x⁴y⁸.
