Is this to easy to ask for the answer?

If so I´m sorry

Ok so this does not make much sense but i think the answer is A. because it makes most sense and if you look up what 3<f means it will give you an explanation on what it means cause I have no idea and at least I tried.

                                    but try A.

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

the correct answer is x/3+10≥32

hope this !
