Hi, good work.
16&#8730;27 + 7&#8730;108 = 90&#8730;3 
16&#8730;9&#8730;3 + 7&#8730;36&#8730;3 
16 . 3&#8730;3 + 7 . 6&#8730;3 
(48 +42)&#8730;3
    90&#8730;3       |yes, right on track!

&#8730;600x^4 = &#8730;100 . &#8730;x^4 . &#8730;6 = 10x^2&#8730;6    
|note: 'x^4'.. until actually taking the square root when showing your work.
