Find the ones digit of 73^340  Choose the correct choice from the following answers
A) 3	B) 5	C) 6	D) 7	E) 9
Cyclicity of 3 is 3,9,7,1after 4 multiplication again the cycle repeats.   So divide 340 by 4 and we get 87 as quotient and 2 as remainder. So cycle will run for 87 times and then 2 times more. So pick up the 2nd item from the cycle.   Hence 3nswer 3.
