Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-7" was replaced by "^(-7)".

(2): "9.12" was replaced by "(912/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-7 = (2•5)^(-7) = (2)^(-7) • (5)^(-7)

Equation at the end of step  1  :

  912
  ——— • ((2)(-7)•(5)(-7))
  100

Step  2  :

            228
 Simplify   ———
            25 

Equation at the end of step  2  :

  228
  ——— • ((2)(-7)•(5)(-7))
  25 

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁷   = 5^{(2 + 7)} = 5⁹

Dividing exponents :

 3.2    2²   divided by   2⁷   = 2^{(2 - 7)} = 2^(-5) = ¹/_2⁵

Final result :

     57                                    
  ——————— = 9.12000 • 10-7 
  (59•25)
