If X=27^324 and Y=3^134, what is the units digit of X/Y?  Choose the correct choice.
A) 1 B) 3 C) 5 D) 7 E) 9
Basically it tests pattern : (3,9,7,1)   If we take write 27 in terms of 3 and take the dr to the top, it will result in 3^838   since pattern = 4 divide 838/4 and reminder = 2 ------- this points to 9 in the pattern (3,9,7,1)   ANSW9R:9
<result>E</result>
