Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-11" was replaced by "^(-11)".

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

Step  1  :

 1.1     10 = 2•5

(10)^-11 = (2•5)^(-11) = (2)^(-11) • (5)^(-11)

Equation at the end of step  1  :

  64
  —— • ((2)(-11)•(5)(-11))
  10

Step  2  :

            32
 Simplify   ——
            5 

Equation at the end of step  2  :

  32
  —— • ((2)(-11)•(5)(-11))
  5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5¹¹   = 5^{(1 + 11)} = 5¹²

Dividing exponents :

 3.2    2⁵   divided by   2¹¹   = 2^{(5 - 11)} = 2^(-6) = ¹/_2⁶

Final result :

      1                                      
  ———————— = 6.40000 • 10-11
