If (1/2)^22 (1/81)^k = 1/18^22, then k = Choose the correct answer:	A) 8	B) 12	C) 16	D) 24	E) 11
I'm going to focus on denominator only..   (2^22) . ((3^4)^k = 18^22   (2^22) . ((3^4k) = (2. 3^2)^22   (2^22) . ((3^4k) = (2^24) . (3^2)^22   hence   4k = 44   k = 11   answer 11   I hope it's quite clear
