Question

There is a question as following
\[0,\overline{1101}=\sum_{k=0}^{\infty}\frac{1}{2^{4k+1}}+\frac{1}{2^{4k+2}}+\frac{1}{2^{4k+4}}\] but i dont understand this following part where the nominators coming \[=\sum_{k=0}^{\infty}\frac{2^{2}.2^{4}+2.2^{4}+2.2^{2}}{2^{4k}.2^{7}}\]

Answer 1

\[\frac{this}{that}\]

Answer 2

Answer 3

sorry my internet connection is bad, i didnt got chance to make it better, now its a little bit better, i will correct it

Answer 4

\[0,\overline{1101}
=\sum_{k=0}^{\infty}\frac{1}{2^{4k+1}}
+\frac{1} {(2^{4k+1})^{2} }
+\frac{1}{(2^{4k+1})^{4}}\]

Answer 5

2^x^k fails
