Show That 12 cos 30° + 2 tan 60° Can Be Written In The Form √k Where k Is An Integer

square root of 192

Step-by-step explanation:

12 cos 30 degrees + 2 tan 60 degrees

= 12* (root 3 /2) + 2* root 3  [as cos 30= root 3/2 and tan 60 = root 3]

=6 root 3 + 2 root 3

= 8 root 3

= square root of 64*3

=square root of 192

= square root of k [ where k = 192 = integer]
