This one is a very old one.
Is x > y?
1) (a^n)*x > (a^n)*y
2) 3n + 1 is odd
open to debate......i hope i don't screw up on this one like the last one
The agreed upon answer for this question by all the members who responded to this question in the past is C.
I have following questios.
(1) Should the second statement be given as 3n + 1 is positive
If the word positive
is not included then we can take
3n + 1 = -1 => n -2/3 = 0.66666..... (Is this odd or even? )
If the word integer
is not included,
Can we consider 3n + 1 = 5.5 ? (This is odd number, correct?)
=> n= 4.5/3 => 1.5 (This should be odd)
I think if these conditions are not included, then the answer should be E.
Finally, please let me know (-1)^1.2 = ?
I thought that 1.2 is considered even number so answer should be 1. But the calculator says invalid input function.
(1.2 here is decimal number = 12/10)[/b]
