Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-9" was replaced by "^(-9)". 1 more similar replacement(s)

(2): "9.9" was replaced by "(99/10)". 2 more similar replacement(s)

Step  1  :

 1.1     10 = 2•5

(10)^-9 = (2•5)^(-9) = (2)^(-9) • (5)^(-9)

Equation at the end of step  1  :

    1         99
  ((—•(10-6))•——)•((2)(-9)•(5)(-9))
    1         10

Step  2  :

            99
 Simplify   ——
            10

Equation at the end of step  2  :

    1             99
  ((— • (10-6)) • ——) • ((2)(-9)•(5)(-9))
    1             10

Step  3  :

 3.1     10 = 2•5

(10)^-6 = (2•5)^(-6) = (2)^(-6) • (5)^(-6)

Equation at the end of step  3  :

    1                        99
  ((— • ((2)(-6)•(5)(-6))) • ——) • ((2)(-9)•(5)(-9))
    1                        10

Step  4  :

            1
 Simplify   —
            1

Equation at the end of step  4  :

                             99
  ((1 • ((2)(-6)•(5)(-6))) • ——) • ((2)(-9)•(5)(-9))
                             10

Step  5  :

Multiplying exponents :

 5.1    2⁶  multiplied by  2¹   = 2^{(6 + 1)} = 2⁷

Multiplying exponents :

 5.2    5⁶  multiplied by  5¹   = 5^{(6 + 1)} = 5⁷

Equation at the end of step  5  :

     99  
  ——————— • ((2)(-9)•(5)(-9))
  (27•57)

Step  6  :

Multiplying exponents :

 6.1    2⁷  multiplied by  2⁹   = 2^{(7 + 9)} = 2¹⁶

Multiplying exponents :

 6.2    5⁷  multiplied by  5⁹   = 5^{(7 + 9)} = 5¹⁶

Final result :

      99                                      
  ————————— = 9.90000 • 10-15 
  (216•516)
