Explicación paso a paso:
1) = 5(-3) x²⁺⁴ = -15x⁶
2) = -12(-5) xy³⁺⁵ = 60xy⁸
3) = 6(-5) x¹⁺⁴ y²⁺⁶ = -30 x⁵ y⁸
4) = 5x(3x-1) + 2(3x-1) = 15x²-5x + 6x-2 = 15x² + x - 2
5) = 6x³⁺¹ - 18x³ + 24x³⁺² = 6x⁴ - 18x³ + 24x⁵ ----reordenando: ----> 24x⁵ + 6x⁴ - 18x³
6) = 7(3)x²⁺⁵ y⁴⁺¹ + 7(4)x² y⁴⁺³ - 7x²⁺⁵ y⁴ = 21x⁷y⁵ + 28x²y⁷ - 7x⁷y⁴
