Question

Choose the correct answer for the problem

Answer 1

5x9y8

Explanation:

Multiplying two negatives equals a positive ( - ) × ( - ) = ( + )

Answer 2

D

Explanation:

You would multiply the -5 and the -1 from the -5x^4 and the -x^5 this would make 5. Also the 4 and the 5 exponets, since they are exponets you need to add if multiplying so it would just be 4+5=9.

For y its just multiplying the exponets which is y^4xy^4=y^8.

Final answer if you bring everything together is 5x^9y^8 also answer D.
