0,4a³*1,5a³b=0,6a^6b

-14a^7b³c^11*2 3/7bc=-14*17/7b^4c^12=-34b^4c^12

0,2m³n^9*2,5m^4n=0,5m^7n^10

45m³n²p^4*1 1/9m^8n^11p^6=45*10/9m^11n^13p^10=50m^11n^13p^10

(-2x³y)³=-8x^9y³

(2 1/3m^24n18)³=(7/3^3m^72n^54)=343/27m^72n^54=12 19/27m^72n^54

(-3xy²)³=-27x³y^6

(1 1/3p^12q^6)²=(4/3)²p^4q^12=16/9p^24q^12

4.

2x^9*(-4a²x^3)²=2x^9*(16a^4x^6)=32a^4x^15

5a^6*(-3d^2b)²=5a^6(9a^4b^2=45a^10b^2
