Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "6.4" was replaced by "(64/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  64
  —— • ((2)(-12)•(5)(-12))
  10

Step  2  :

            32
 Simplify   ——
            5 

Equation at the end of step  2  :

  32
  —— • ((2)(-12)•(5)(-12))
  5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5¹²   = 5^{(1 + 12)} = 5¹³

Dividing exponents :

 3.2    2⁵   divided by   2¹²   = 2^{(5 - 12)} = 2^(-7) = ¹/_2⁷

Final result :

      1                                      
  ———————— = 6.40000 • 10-12
