If (1/2)^23 (1/81)^k = 1/18^23, then k =	Choose the correct choice from the following answers:
A) 8	B) 12	C) 16	D) 24	E) 46/4
I'm going to focus on denominator only..   (2^23) . ((3^4)^k = 18^23   (2^23) . ((3^4k) = (2. 3^2)^23   (2^23) . ((3^4k) = (2^23) . (3^2)^23   hence   4k = 46   k = 46/4   answer 46/4   I hope it's quite clear
