Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-3" was replaced by "^(-3)".

Step  1  :

 1.1     81 = 34

(81)^-3 = (3⁴)^(-3) = (3)^(-12)

Equation at the end of step  1  :

     16   
  ———————— ÷ 4
  (3)(-12) 

Step  2  :

                  1 
 Divide  16  by  ———
                 312

Equation at the end of step  2  :

  (24•312) 
  ————————
     4    

Step  3  :

            (24•312) 
 Simplify   ————————
               4    

Dividing exponents :

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

Final result :

  (22•312)
