\(a^b=c\)

If a, b and c are integers, what is the value of a?

(1) c=1

(2) b≠0

Given : a, b and c are integers

DS : a^b = c

Option 1 : c=1

a^b = 1, b = 0 then in that case a can assume any value.

NOT SUFFICIENT ...

Option 2: a^b = c b=/=0 .. This doesn't give us much idea about a.

Combined :

a^b = 1 and b=/=0

So a =1, b=1,2,3,4,...............

a=-1, b = 2,4,6,8,...........

So even combined options don't give one single value of a

Hence E is correct.
