Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-7" was replaced by "^(-7)".

(2): "1.61" was replaced by "(161/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-7 = (2•5)^(-7) = (2)^(-7) • (5)^(-7)

Equation at the end of step  1  :

  161
  ——— • ((2)(-7)•(5)(-7))
  100

Step  2  :

            161
 Simplify   ———
            100

Equation at the end of step  2  :

  161
  ——— • ((2)(-7)•(5)(-7))
  100

Step  3  :

Multiplying exponents :

 3.1    2²  multiplied by  2⁷   = 2^{(2 + 7)} = 2⁹

Multiplying exponents :

 3.2    5²  multiplied by  5⁷   = 5^{(2 + 7)} = 5⁹

Final result :

    161                                    
  ——————— = 1.61000 • 10-7
