Question

Any help would be great

Answer 1

Hey there! :)

Answer:

`-25m^(6)n^(9)`

Explanation:

The product rule means that when multiplying variables with exponents, the exponents must be added together. Therefore:

`(-5m^(5)n^(6))(5mn^(3)) =`

`-25m^(5+1)n^(6+3) =`

Simplify:

`-25m^(6)n^(9)`

This is your answer!
