Question

6u^9+(8u^9+4v) please help asap brainliest if you get it right

Answer 1

I think you need to add if you want to find out the variable u or v, but I'm going to assume you mean to simplify the problem.
Your answer is 14u^9+4v.
Hope I could help :)

Answer 2

6u^9+(8u^9+4v) 
= 6u^9 + 8u^9 + 4v
= 14u^9 + 4v
