What is the product of 5ab and (-2a²b)³?

-40a^6b^4
-30a^7b^4
-40a^7b^4
-30a^6b^4

The product would be -40a^7b^4

Step-by-step explanation:

In order to find this, we first need to expand the parenthesis with the power.

(-2a^2b)^3 = 8a^6b^3

Now we can take the expanded form and multiply it by the other term.

8a^6b^3 * 5ab = -40a^7b^4

20
