n^4<25
n^2<5
so n can be 1 or 2

n does not equal to n^2
so n cant be 1

therefore, n=2

WHAT IS THE VALUE OF THE POSITIVE INTIGER N

1) N^4<25
2) N not = N^2

1) N^4 < 25; N = 1, 2 since 1^4 <25 and 2^4 <25 and N is +ve integer.
UNSUFF.

2) Clearly Unsuff.

Combining
N can not be 1. So N=2

OA is C.
