    ( 4^5. 10 .5^6 . 2^8) : ( 2^8 . 5^4 + 5^7 . 2^5)
    = ( 4^5. 10 .5^6 . 2^8)/( 2^8 . 5^4 + 5^7 . 2^5)
    = ((2^2)^5 . 2 . 5 . 5^6 . 2^8)/(2^5 . 5^4 . (2^3 + 5^3))
    = (2^10 . 2 . 5 . 5^6 . 2^8)/(2^5 . 5^4 . (8 + 125))
    = (2^19 . 5^7)/(2^5 . 5^4 . 133)
    = (2^14 . 5^3)/133
    = (16384 . 125)/133
    = 2048000/133

    (4^5 . 10 . 5^6 . 2^8) : (2^8 . 5^4 + 5^7 . 2^5)
    =(2^10 . 2 . 5 . 5^6 . 2^8) : [2^5 . 5^4 . (2^3 + 5^3)]
    =(2^19 . 5^7) : (2^5 . 5^4 . 133)
    =$\dfrac{2^{19}.5^{7}}{2^{5} . {5^4} . 133}$ 
    =$\dfrac{2^{14}.5^{3}}{133}$ 
    = $\dfrac{16384.125}{133}$ 
    =2048000/133
