7m² * 6c³m = 42c³m³

-6m^8 * 9am³ = -54am^11

3m²np * (-5mn² * 4) = -60m³n³p

ab * 9a * 4b = 36a²b²

Ответ:

2)42m^3c^3  3)-54m^11a 5)-60m^3*n^3*p 6)36a^2b^2

Объяснение:

2) 42m^2*c^3*m^1= 42m^2+1*c^3=42m^3*c^3

3) -54m^8+3 *a=-54m^11*a

5) 3m^2np*(-20mn^2)= -60m^3*n^3*p

6) a^1b^1*36a^1b^1=a^1+1b^1+1*36=a^2b^2*36=36a^2b^2
