A. 12x3y2
B. –3xy2
C. 3xy2
D. –12x3y2

Answer 1

I think it’s d I’m not sure

Answer 2

For this case we must find the product of the following expression:

`-2x * (- 3x^2y) * (2y) =`

We take into account that:

`- * - = +`

To multiply powers of the same base, the same base is placed and the exponents are added:

`6x^(1 + 2)y * 2y =\\6x ^ 3 * 2y ^ {1 + 1} =\\12x ^ 3y ^ 2`

ANswer:

`12x ^ 3y ^ 2`
