1) 5 * (3mn)*(6m) = 5*3*6m¹⁺¹n = 90m²n;
2) (8xyz) * (4yz) = 8*4xy¹⁺¹z¹⁺¹ = 32xy²z²;
3) 10 * (2bmn) * (2/5m) = 10*2*2/5bm¹⁺¹n = 8bm²n;
4) 6 * (3kbc) * (-5pkc) = 6*3*(-5)bc¹⁺¹k¹⁺¹p = -90bc²k²p.
3.
1) (5с)³ = 125с³;
2) (1/8 b)² = 1/64 b²;
3) (2х²у)³ = 8х⁶у³;
4) (-1/3 m³n⁴)³ = -1/27 m⁹n¹².
4.
-5/64 ху² * (4/5 х²у)² = х= -2; у= -1/2;
= -5/64 ху² * 16/25 х⁴у² =
= -1/20 х¹⁺⁴у²⁺² =
= -1/20 х⁵у⁴ =
= -0,05 * (-2)⁵ * (-0,5)⁴ =
= -0,05 * (-32) * 0,0625 =
= 0,1.
