If m and n are positive, what is m * n ?

1. m^n = 1
2. n^m = 1
(C) 2008 GMAT Club - m13#1

Statement (1) ALONE is sufficient, but Statement (2) ALONE is not sufficient
Statement (2) ALONE is sufficient, but Statement (1) ALONE is not sufficient
BOTH statements TOGETHER are sufficient, but NEITHER statement ALONE is sufficient
EACH statement ALONE is sufficient
Statements (1) and (2) TOGETHER are NOT sufficient

OE: Statement (1) by itself is insufficient. If m is 1, n can be any integer.

Statement (2) by itself is insufficient. If n is 1, m can be any integer.

Statements (1) and (2) combined are sufficient. From S1 and S2, it follows that m = n = 1.

The correct answer is C.
--
As I think, we have one more option - when both m & n equals to 0.

Am I right?

Hi,

Any number, except 0, raised to the power zero has a numerical value of 1.
0 raised to power 0 is not defined.

regards,

In mathematics there are varying opinions on whether 0^0 equal 1 or whether it is undefined. The writers of the Gmat Club tests apparently assumed that 0^0 is undefined (hence choice C and not E).

This concept is not tested on the actual GMAT.

Ok, thank you! Let's hope that I wouldn't face such controversial matters on the test day! :?
