= 2^10 . ( 13 + 65 ) / 2^8 . 104

= 2^10 . 78 / 2^8 . 104 

= 2 . 2 . 2^8 . 78 / 2^8 . 104

= 2^8 . 312 / 104

\(\frac{2^{10}.13+2^{10}.65}{2^8.104}=\frac{2^{10}.13+2^{10}.13.5}{2^8.2^3.13}\)

                              \(=\frac{2^{10}.13+2^{10}.13.5}{2^{11}.13}\)

                              \(=\frac{2^{10}.13\left(1+5\right)}{2^{11}.13}\)

                              \(=\frac{2^{10}.13.6}{2^{11}.13}\)

                              \(=\frac{2^{11}.13.3}{2^{11}.13}=3\)
