Sometimes radical questions are really hard to figure out, but
this one should work out pretty well.
First work on \/81 ( that is how I will notate radical)
What is the number that when squared gives us 81?
I hope you see that it is 9. So the first part is 3*9,
which is 27.
How would you figure out the second part?
Then after you have the two parts add them together.
Hope that helps.
