is 1/a < a / (b^4) + 3
(1) since a can't be 0, b also can't be 0 because a^2=b^2.......any other number works here though the only problem is the sign....-1 AND 1 can work. Hence this statement by itself is insufficient.
1/(-1) < -1 / (1)^4 + 3 --> -1 < -1/4 << YES!!
1/1 < 1/1^4+3 = 1 < 1/4 << NO!!
a^2=b^4 runs into the same problem as (1). since both exponents are even, they hide the sign of their base.
Together: Doesent really make a difference. Again sign of base is hidden.
In a question like this where both statements are giving you the exact same information, the answer is usually (D) or (E)........
(A) doesent make sense to me
