Solution - Power equations

Step  1  :

            16
 Simplify   ——
            81

Equation at the end of step  1  :

  16
 (——)1) ÷ 4
  81

Step  2  :

 2.1     16 = 24

(16)¹ = (2⁴)¹ = 2⁴  2.2     81 = 3⁴ (81)¹ = (3⁴)¹ = 3⁴

Equation at the end of step  2  :

  24
  —— ÷ 4
  34

Step  3  :

         24      
 Divide  ——  by  4
         34      

Dividing exponents :

 3.1    2⁴   divided by   2²   = 2^{(4 - 2)} = 2²

Final result :

   4           
  —— = 0.04938
