How do you get 100 with ONLY the numbers 3 4 and 4

(3+4)*(3+4)*(3-4/4)+(3-4/4)=100     

What I meant was, you can only use three once and four twice...

Well, are you going to give us a hint?  

So heres my try on the puzzle. (A bit late ik)

Well I dont have a really good answer.

I first tried to get an answer without decimals( didnt really worked out) the farthest i went with that was 99

without having decimal numbers:

4! * 4 + 3 = 99

But jea i then tried to get 100 by using exponential numbers and then using the gauss bracket to get 100.

Im not sure if this kinda cheating but i got 2 results: (and im not sure if this is the right way to use the brackets)

Gauss bracket [ 3^ 4.sqrt(4) ] = [3^4.2] = [100.9...] = 100

Gauss bracket [ 4! * 4.sqrt(3) ] = [24 * 4.1732... ] = [100.15692...] = 100
