Let x = 2^11then E = (x+x^2+x^3)/(x^3 - 1)using difference of cubes formula in denominator = x/(x-1)= 2048/2047
Very nice! ❤
{2^11)^3-1^3}=(2^11 -1)(2^22 +2^11 +1)&2^11)(2^22+2^11 +1)Finally2^11//(2^11-1)=1//{1 -2^-11)
2048/2047
Use sum of gp🥱🥱
Let x = 2^11
then
E = (x+x^2+x^3)/(x^3 - 1)
using difference of cubes formula in denominator
= x/(x-1)
= 2048/2047
Very nice! ❤
{2^11)^3-1^3}
=(2^11 -1)(2^22 +2^11 +1)
&2^11)(2^22+2^11 +1)
Finally
2^11//(2^11-1)
=1//{1 -2^-11)
