Solution - Power equations

Step  1  :

             8
 Simplify   ——
            27

Equation at the end of step  1  :

  (8
 (——)3) ÷ 4
  27

Step  2  :

 2.1     8 = 23

(8)³ = (2³)³ = 2⁹  2.2     27 = 3³ (27)³ = (3³)³ = 3⁹

Equation at the end of step  2  :

  29
  —— ÷ 4
  39

Step  3  :

         29      
 Divide  ——  by  4
         39      

Dividing exponents :

 3.1    2⁹   divided by   2²   = 2^{(9 - 2)} = 2⁷

Final result :

  128
