If n is a nonzero integer, is x^n < 1?
(1) x > 1. If x = 2 and n = 1, then the answer is NO but if x = 2 and n = -1
, then the answer is YES.
(2) n > 0. If x = 2 and n = 1, then the answer is NO but if x = 1/2 and n = 1, then the answer is YES.
(1)+(2) x is greater than 1 and n is a positive number: any number greater than 1 in positive power is greater than 1. Sufficient.
Answer: C.
I have just 1 query, why you have consider x as an integer only because if you assume any value non integer then ans will be no
Shade your thoughts
