7 & 11&5&3 are also factors of 1155 ... //0,2,4,8,6 comes as last digit 2^n , on substracting 1... we get 9,1,3,7,5 as last digit , still some possibility of getting divisible bcz of 5 as last digit also possible & now what ? //there are numbers possible which have last digit as 5 & div. by 7,11&3 ... //i am also confused 😅

take log ☺👍 use log2=.3010 & log as .4771 log y = 2^2007+ 3^2008 -2009 . log2 //will see 1 later y=10^((2^2007+3^2008-2009).log2) =10^(10^(2007.log2)+10^(2008.log3)-2009) . log2 then check whether y-1 is div by 1155 or not
