16√27 + 7√108 = 90√3
16√9√3 + 7√36√3
16 . 3√3 + 7 . 6√3
(48 +42)√3
90√3;
And
√600x^4 = √100 . √x^2 . √6 = 10x^2√6

Hi, good work.

16√27 + 7√108 = 90√3 

16√9√3 + 7√36√3 

16 . 3√3 + 7 . 6√3 

(48 +42)√3

    90√3       |yes, right on track!



√600x^4 = √100 . √x^4 . √6 = 10x^2√6    

|note: 'x^4'.. until actually taking the square root when showing your work.
