Answer 1

Powinno być dobrze . ; ]

a . (-4) *2* (-3 1/8) *1/5 -= -8*(-25/8)*1/5 =-8*(-5/8)=5

b.(-0,1) * x * 10xy²=(-0,1x)*10xy²=x²y²

c. (-a)* 6x²y *(-5y) * (-0,4)= (-6x²ya)*(-5y)*(-0,4)=30x²y²a*(-0,4)=-12x²y²a

d.1/2 *x*x*x*(-2y)* (-y) * (-y) = 1/2*x [do potęgi 3]*-2y*-y*-y=1/2x[do potęgi 3]*-2y[do potęgi 3]= -x[dopotęgi 3]*y[do potęgi 3]

e.1/2 ababababab * (-2)= (-ababababab)

f. (-1)*(-1)*(-1)* xyxy * (-1)= 1*(-1)*xyxy*(-1)= (-1)*xyxy*(-1)= (-xyxy)*(-1)=xyxy

g.(-3)² * (-3) * a²bb * (-3)=9*(-3)*a²bb*(-3)=27*a²bb*(-3)=27a²bb*(-3)= (-81a²bb )

h.6mn * 1/3 m³ * (-2)*n =2m[do potęgi 4]n*(-2)*n= -4m[do potęgi 4]n*n=-4m[do potęgi 4]n²
