lets say we hv nmbers... 1,2,3,4 nd 5.... no of arrangements of a 5 digit nmber if digits can be repeated.... in first digit we can choose frm 5 digits, so 5 possibilites..as the digits can be repeated hence we again hv 5 possibilities fr 2nd digit... so total arrangements are 5x5x5x5x5=5^5 if... -
