Question

Someone please help me with this question (-3b)3 (-2a)3

Answer 1

Step-by-step explanation:

I think the Q is (-3b)^3(-2a)^3

we can take the minus sign out of the-(2a)^3

Now: (-3b)^3-(2a)^3=a^3-b^3=a^3-b^3-3ab(a-b)

a=-3b b=2a

(-3b)^3-(2a)^3-3(-3b×2a)(-3b-2a)

-27b^3-8a^3+18ab(-3b-2a)

-27b^3-8a^3-54ab^2-36a^2b

I think u Understand the answer.
