(3m)=27m

(2cd)=8cd

(-)=-y

(-y)=-x^6y^3

-(cm^4)=c^4m^16

(x^7)=x^21

Ответ:

Пошаговое объяснение:

1) (3m)³ = (3*3*3) * (m*m*m) = 27m³

2) (2c²d)³ = (2*2*2) * c^6 * d³ = 8c^6 d³

3) (-y^5 x²)³ = -y^15 x^6

4) (-1/4x²y)³ = -1/64x^6 y³

5) (-2/3cm⁴)³ = -8/27c³m¹²

6) (1. 1/4x^7)³ = (5/4x^7)³ = 125/64x²¹
