    \frac{2^{10} . 13 + 2^{10} . 65}{2^8 . 104}
    = \frac{2^{10}.(13 + 65)}{2^{8}.2.2.2.13}
    = \frac{2^{10}.78}{2^{11}.13}
    = \frac{2^{11}.3.13}{2^{11}.13}
    = \frac{3}{1} = 3

    ( 2^10 × 13 + 2^10 × 65 )/( 2^8 × 104 )
    = ( 2^10 × 13 + 65 )/( 2^8 × 104 )
    = ( 2^8 + 4 × 78 )/( 2^8 × 104 )
    = ( 2^8 + 312 )/( 2^8 × 104 )
    = 312/104
    = 3
