Physics, F=MA Help!!?

Hm. 2+2=4 subtract 2 from 4 to get the divided variable. 4 to the power of 4 is 1 divided by 2 = 8. Now you have the common denominator. Subtract the positive integer and round the decimal. Now you have the mixed fraction. This should be the answer to my math homework. Anyway, back to your question... I don't know.
