n is any odd positive integer
please find the last two digits of :$2^{2n}(2^{2n+1}-1)$
please find the last two digits of :$2^{2n}(2^{2n+1}-1)$
yes please go aheadIn the end we would be proving A4 X (2A)7
or A4 X (2A-10)7 = ....28
where A,4,(2A),(2a-1) and 7 are digits....
let n=2m+1 (m=0,1,2,3,4,5----)n is any odd positive integer
please find the last two digits of :$2^{2n}(2^{2n+1}-1)$
