Question

выполните умножение пж помогите

Answer 1

Объяснение:

-3a³-6a²+15ab;

-10y³+5y⁶-40y;

0,6m²n³-1,2m³n²+0,9m²n²;

7a²b³-2a³b²+16a³/21;

x^2n+5 - 2x^2n+2 + x^3n+1;

Answer 2

Ответ:

-3a(a²+2ab-5b) = -3a³-6a²b+15ab

(4y²-2y⁵+16)(-2,5y) = -10y³+5y⁶-40y

0,3mn(2mn²-4m²n+3mn) = 0,6m²n³-1,2m³n²+0,9m²n²

1 3/4 a²b(4b²-8/7 ab)+16/21 a³ = 7/4a²b(4b²-8/7 ab)+16/21 a³ = 7a²b³-2a³b²+16/21 a³

x^n+2 *(x^n+3 -2x^n +x^2n-1) = x^2n+5 -2x^2n+2 +x^3n+1
