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): "4.3" was replaced by "(43/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  )43
  ——— • ((2)(-7)•(5)(-7)))
  (10

Step  2  :

            43
 Simplify   ——
            10

Equation at the end of step  2  :

  )43
  ——— • ((2)(-7)•(5)(-7)))
  (10

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2⁷   = 2^{(1 + 7)} = 2⁸

Raising to a Power :

 3.2    5¹  multiplied by  5⁷   = 5^{(1 + 7)} = 5⁸

Equation at the end of step  3  :

  8))43 
  ———————
  (28•58)

Step  4  :

 4.1     10 = 2•5

(10)⁸ = (2•5)⁸ = 2⁸ • 5⁸

Equation at the end of step  4  :

  8))43 
  ———————
  (28•58)

Step  5  :

Equation at the end of step  5  :

  8)43 
  ———————
  (28•58)

Step  6  :

                           43  
 Divide  (3•28•58)  by  ———————
                        (28•58)

Multiplying exponents :

 6.1    2⁸  multiplied by  2⁸   = 2^{(8 + 8)} = 2¹⁶

Multiplying exponents :

 6.2    5⁸  multiplied by  5⁸   = 5^{(8 + 8)} = 5¹⁶

Final result :

  (3•216•516)                                   
  ——————————— = 6.97674 • 1014
