Answer 2

Let's break down each term and simplify them one by one using trigonometric identities:

2sin 60° = 2(√3/2) = √3

4cos 60° = 4(1/2) = 2

ctg30° = 1/tan30° = 1/(√3/3) = √3/3

tg45° = 1

Now we can substitute these values back into the original expression:

2sin 60° + 4cos 60° - ctg30° - 2tg45° = √3 + 2 - √3/3 - 2 = (√3 - √3/3) + (2 - 2) = 2√3/3

Therefore, the simplified expression is 2√3/3.
