When the radical terms are the same, just focus on the numbers that are in front of them so it's really just 6 - 9 and you get -3 (third root of 2b)
Answer:

Step-by-step explanation:
Let us apply the distributive property to find an equivalent expression for:

For all real numbers a, b, and c, the distributive property says that:

We apply this property to get:


We simplify the RHS to get:

It would be 8xy
Because you would multiply the 2 numbers together
