how ddo we pronounce 4e and as far as I learn from this site tak means yes so what is the purpose of using tak here
By "4e" you mean "це"? :) Check out forvo.com, they have a lot of samples from native speakers.
"Так" means "yes" but also "so", "this way", "like that". So in this case it means "it is not so", "it is not like that".
If I understand correctly, так in this sentence acts exactly like its Russian cognate, which is an adverb, right?
Так can also mean 'so': 'so much' - так багато
We'll do it this way - ми зробимо це так
When would you use ні and when не? Is there a difference?
Ні means no and не means not.
