Hello KSBGC!!!

Is there any concept that we can learn in order to answer these questions without trying with some numbers?

I know that the only possible answer was 3 but I had to try some numbers first.

Kind regards!

IMO:- In Gmat, Even if there is a formula to solve some type of questions, you can rely on it..you have to use the logic all the time

There is only one integer k=3, when $$3^3$$ =$$3^3$$ . Answer (B)

B
because 3^k can equal to k^3 only if k is 3 = 3^3=3^3.
