<PRE><B>Question 1154941</B>
hard to guess what is given

if you have an image, go to

https://imgur.com/upload?beta

upload image, copy link, and post it here


my best guess is that you are given 


{{{3root(3,81)+root(3,2187)}}} and you need to simplify it


{{{3root(3,3*3^3)+root(3,3*9^3)}}} 


={{{3*3root(3,3)+9root(3,3)}}} 


={{{9root(3,3)+9root(3,3)}}} 


={{{18root(3,3)}}}
