Step  1  :

 1.1     4 = 22

(4)^-1 = (2²)^(-1) = (2)^(-2)

Equation at the end of step  1  :

Step  2  :

 2.1     4 = 22

(4)^-3 = (2²)^(-3) = (2)^(-6)

Equation at the end of step  2  :

Step  3  :

 Divide  ——  by  (2)(-2)
         26      

 3.1    Dividing fractions

To divide fractions, write the divison as multiplication by the reciprocal of the divisor :

 1      1        1     22
——  ÷  ——   =   ——  •  ——
26     22       26     1 

Dividing exponents :

 3.2    2²   divided by   2⁶   = 2^{(2 - 6)} = 2^(-4) = ¹/_2⁴

Final result :

   1           
  —— = 0.06250
