What is the answer .

B

Step-by-step explanation: I first simplified the expression which gave me 6^6 x 1/6^8 then, I reduced the expression with 6^6 which is now 1/6^2. After, I evaluated the power which is now 1/26. So the answer is B.

(n^3 - n)

= n(n-1)(n+1)

since it is divisible by 3 and 2 ,because it is a multiple 3 consecutive number

if, n-1 is odd then n+1 is also odd, then it is a multiple of 9

but if, n-1 is even then n+1 is also even, then it is a multiple of 4

so, largest multiple = max(9*2, 4*3) = max(18, 12) = 18

if you explain the the question more correctly i might be able to answer this better
