the one on the right is correct

No, it isn't.

8/2×(2+2)

...isn't the same thing as 8/2(2+2). You separated the term in the denominator, leading the (2+2) to get flipped into the numerator, hence wrong answer.

That would be 8/(2x(2+2)) if we were keeping it all in the denominator. Multiplication happens in the numerator if there are no parenthesis to distinguish it. If thr equation was written like this:

8


2x(2+2)

Then you would also be correct, but I have to respectfully disagree with your analysis.

(2x(2+2)) is the same thing as 2(2+2)

Which means you disagree with how Maths textbooks teach how to do this (see previous link).
