Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-5" was replaced by "^(-5)".

(2): "7.85" was replaced by "(785/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  785
  ——— • ((2)(-5)•(5)(-5))
  100

Step  2  :

            157
 Simplify   ———
            20 

Equation at the end of step  2  :

  157
  ——— • ((2)(-5)•(5)(-5))
  20 

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2⁵   = 2^{(2 + 5)} = 2⁷

Multiplying exponents :

 3.2    5¹  multiplied by  5⁵   = 5^{(1 + 5)} = 5⁶

Final result :

    157             
  ——————— = 0.00008 
  (27•56)
