Question

Select the product of (-2x9y)(x7y6).

A. 2x16y7

B. -2x16y7

C. -2x63y2

D. 2x63y6

 

 

Which is it?

Answer 1

I'm going to assume that the problem is:

 

(-2x⁹y)(x⁷y⁶)

 

When you multiple terms with exponents, you add the exponents:

 

-2x⁽⁹⁺⁷⁾y⁽¹⁺⁶⁾

 

-2x¹⁶y⁷

 

If I interpreted the problem correctly, the answer should be B.
