Виконайте множення:
1) (b3 – d2)(b6 + b3d3 + d4) = ((b3)3 – (d2)3 = b9 – d6;
2) (c3 + 2p)(c6 – 2pc3+ 4p2) = ((c3)3 + (2p)3 = c9 + 8p3;
3) (9x2 + 3xy + y2) (3x – y) = ((3x)3 – y3 = 27x3 – y3;
4) (4c + 3d)(16c2 – 12cd + 9d2) = ((4c)3 + (3d)3 = 64c3 + 27d3;
5) (a8 – 4a4 + 16)(a4 + 4) = ((a4)3 + 43 = a12 + 64;
6) (5m2 – 6р3)(25m4 + 30m2p3 + 36p6) = ((5m2)3 – (6p3)3 = 125m6 – 216p9.
