(1): "^-10" was replaced by "^(-10)".

Step  1  :

 1.1     4 = 22

(4)² = (2²)² = 2⁴

Equation at the end of step  1  :

   (2-10)
  {——————}7
     24  

Step  2  :

Equation at the end of step  2  :

   (2)(-10) 
  {————————}7
      24   

Step  3  :

          1       
 Divide  ———  by  24
         210      

Multiplying exponents :

 3.1    2¹⁰  multiplied by  2⁴   = 2^{(10 + 4)} = 2¹⁴

Equation at the end of step  3  :

   1 
 (———)7
  214

Step  4  :

Final result :

   1                                    
  ——— = 3.15544 • 10-30
