Solution - Raising to a power

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "5.4" was replaced by "(54/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-1 = (2•5)^(-1) = (2)^(-1) • (5)^(-1)

Equation at the end of step  1  :

   54
  (—— • ((2)(-1)•(5)(-1))) • 7
   10

Step  2  :

            27
 Simplify   ——
            5 

Equation at the end of step  2  :

   27
  (—— • ((2)(-1)•(5)(-1))) • 7
   5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5¹   = 5^{(1 + 1)} = 5²

Equation at the end of step  3  :

  27
  —— • 7
  50

Step  4  :

Final result :

  189
