Thanks, to solve it quickly i thought it as cubic overlooking the fact that it is actually a^-3, not a^3.

If 1/a^3+ a^2+ 9=0 , is ''a'' greater than/less than or equal to -1/3. This a GRE question. Thanks!

i have gone through the question again and the 4th choice is (s+t+u)10^6. do u think this could be the answer?

I don't know the answer honestly. I know it all depends on the size of proper fractions also what happens if all the fractions are equal. I'll appreciate if anyone can explain the strategy to solve such questions quickly. thanks

If 0< s,t,u<1 then which of the following is close to s+(s+t)10^6+u10^12 1. (s+t+u)10^12 2. 10^12 3. 10^18 OR what else do u think is the answer?
