(2⁶)⁷ ·(2⁻²)⁻⁸· 2⁻²⁰

Answer 1

   2^81 * 4^-3 *(1/2)^40

--------------------------------  = 

 (2^6)^7 *(2^-2)^-8 * 2^-20

 

 

    2^81 *(2^2)^-3 * 2^-40

= -----------------------------  = 

    2^42 * 2^16 * 2^-20

 

      2^81 * 2^-^ * 2^-40

=  --------------------------   =

          2^58 * 2^-20

 

=  2^35 :2^38 = 2^-3 = (1/2)^3 = 1/8
