Step by Step Solution
Reformatting the input :
Changes made to your input should not affect the solution:
 (1): "^-8" was replaced by "^(-8)". 
 (2): "5.5" was replaced by "(55/10)".
Step 1 :
1.1 10 = 2•5
(10)-8 = (2•5)(-8) = (2)(-8) • (5)(-8)
Equation at the end of step 1 :
  55
  —— • ((2)(-8)•(5)(-8))
  10
Step 2 :
            11
 Simplify   ——
            2 
Equation at the end of step 2 :
  11
  —— • ((2)(-8)•(5)(-8))
  2 
Step 3 :
Multiplying exponents :
3.1 21 multiplied by 28 = 2(1 + 8) = 29
Final result :
     11                                    
  ——————— = 5.50000 • 10-8 
  (29•58)
