Please help me with this, I keep getting the wrong answers, this seems pretty obvious. Thanks !

3√108 + 6√27 = 3 • 6 √3 + 6 • 3 √3 = 36 √3

108/27 = 4 so 3 root (108) = 3root (4*27) = 6root 27
6root 27 +6 root 27 = 12 root 27 = 12 root (9*3) = 36root3
6root 27 +6 root 27 = 12 root 27 = 12 root (9*3) = 36root3

3√108 +6√27=3√(36*3) +6√(9*3)=
18√3+18√3 = 36√3
18√3+18√3 = 36√3
