The answer is: 1/1,296 .
_______________________________________________________
6⁻³ / 6¹ = 6⁽⁻³⁻¹⁾ = 6⁻⁴ = 1/6⁴ = 1/ (6 * 6 * 6 * 6) = 1/1,296 .
_______________________________________________________
Or;
_______________________________________________________
6⁻³ / 6¹ = (1/6³) ÷ 6¹ = (1/6³) ÷ 6 = (1/6³) *(1/6 ) = (1*1) /(6³ * 6) ;
_______________________________________________________
= 1/(6³ * 6¹) ;
_______________________________________________________
= 1/(6⁽³⁺¹⁾) ;
_______________________________________________________
= 1 / 6⁴ ;
_______________________________________________________
= 1/ (6*6*6*6) ;
_______________________________________________________
= 1/ 1,296 .
