b) -75x⁴y²z²

c) 60x⁶y⁴

d) -12x⁴y³

e) 60x⁴

f) 24x⁵

g) 72x³y³

h) -6xy⁵z⁴

i) 280x⁴y³

j) 0

Explicación paso a paso:

a) 7(10) = 70 (x)(x)= x² = 70x²

b) -15(5)= -75 (x²)(x²)= x⁴ ,y² ,z²

c) 4(15)= 60 (x³)(x³)= x⁶ (y²)(y²) = y⁴ = 60x⁶y⁴

d) 2(3)= 6(-2)= -12 (x)(x)(x²) = x⁴ (y)(y²)= y³ = -12x⁴y³

e) 6(5)= 30 + 3(10) = 30 = 60 (x)(x³)= x⁴ + (x²)(x²) =x⁴ = x⁴+x⁴= x⁴ = 60x⁴

f) 3(8) = 24 x³(x²)= x⁵= 24x⁵

g) 6(12)= 72 x(x²)= x³ y(y²) = y³ = 72x³y³

h) -3(2)= -6 y⁴(y)= y⁵ z(z³)= z⁴ x =-6xy⁵z⁴

i) 10(7)= 70(4) 280 x(x²)(x)= x⁴ y(²)=y³ = 280x⁴y³

j) 9- (3)(3)= 9-9= 0 x(x³)= x⁴ - x²(x²)= x⁴ = x⁴- x⁴= 0 y - y = 0 = 0
