2 bình luận về “X-12:2mũ2=2mũ4 (X-12):2mũ2=2 mũ4”

1. Giải đáp:

    x-12:2^{2}=2^{4}

   => x-12:4=16

   => x-3=16

   => x=16+3

   => x=19

   Vậy x=19

   ________________

   (x-12):2^{2}=2^{4}

   => x-12=2^{4}.2^{2}

   => x-12=2^{4+2}

   => x-12=2^{6}

   => x-12=64

   => x=64+12

   => x=76

   Vậy x=76
