n^(n/2)=4 is true when n=4 in the same way what is the value of n if n^(n/2) =8?
Choose the most appropriate option: A) 4 B) 8 C) 2 D) 6 E) 10

Rationale: n ^ ( n / 2 ) = 8 apply log n / 2 logn = log 8 nlogn = 2 log 8 = log 8 ^ 2 = log 64 logn = log 64 now apply antilog n = 64 / n now n = 8 . answer : b
Answer: B
