  1. ( 2^3 . 9^4 + 9^3 . 45 ) : ( 9^2 . 10 – 9^2 )
    = ( 8 . 6561 + 729 . 45 ) : 9^2 . ( 10 – 1 )
    = ( 52488 – 32805 ) : 81 . 9
    = 19683 : 729
    = 27
    #dtkc

  2. ( 2^{3} xx 9^{4} + 9^{3} xx 45} ) : ( 9^{2} xx 10 – 9^{2} )
    = ( 8 xx 6561 + 729 xx 45) : ( 81 xx 10 – 81 )
    = 19683 : 729
    = 27
