Question

Rozwiąż działania:

5(2x-8)

6*(12a-4b)

8x*(x-y)

10 ab*(x-3y)

14z(5-25y)

6x(36-7y)

Answer 1

5(2x-8) = 10x-45

6*(12a-4b)= 72a-24b

8x*(x-y)= 8x^2-8xy

10 ab*(x-3y)=10abx-30aby

14z(5-25y)=70z-350zy

6x(36-7y)=216x-42xy

Answer 2

5(2x-8)=10x-40

6*(12a-4b)=72a-24b

8x*(x-y)=8x^2-8xy   (ten znaczek ^ oznacza do kwadratu :D)

10 ab*(x-3y)=10abx-30aby

14z(5-25y)=70z-350y

6x(36-7y)=216x-42xy
