  1. a= $\frac{(3.4.2^{16})^2}{11-(-16)^9}$
    = $\frac{3^2.4^2(2^{16})^2}{11-(-2^4)^9}$
    = $\frac{3^2.4^2.2^{16.2}}{11+(2^4)^9}$
    = $\frac{144.2^{32}}{2^{36}+11}$ 
    = 206158430208/22906492249

  2. A = ( ( 3 xx 4 xx 2^16 )^2 )/( 11 xx 2^13 xx 4^11 – 16^9 )
    A = ( 3^2 xx 4^2 xx 2^32 )/( 11 xx 2^13 xx ( 2^2 )^11 – ( 2^4 )^9 )
    A = ( 9 xx ( 2^2 )^2 xx 2^32 )/( 11 xx 2^13 xx 2^22 – 2^36 )
    A = ( 9 xx 2^4 xx 2^32 )/( 11 xx 2^35 – 2^35 xx 2 )
    A = ( 9 xx 2^36 )/( 2^35 xx ( 11 – 2 ) )
    A = ( 9 xx 2^36 )/( 2^35 xx 9 )
    A = 2
    Vậy , A = 2 .
