Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-12" was replaced by "^(-12)".

(2): "8.7" was replaced by "(87/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-12 = (2•5)^(-12) = (2)^(-12) • (5)^(-12)

Equation at the end of step  1  :

  87
  —— • ((2)(-12)•(5)(-12))
  10

Step  2  :

            87
 Simplify   ——
            10

Equation at the end of step  2  :

  87
  —— • ((2)(-12)•(5)(-12))
  10

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2¹²   = 2^{(1 + 12)} = 2¹³

Multiplying exponents :

 3.2    5¹  multiplied by  5¹²   = 5^{(1 + 12)} = 5¹³

Final result :

      87                                      
  ————————— = 8.70000 • 10-12 
  (213•513)
