(1): "^-77" was replaced by "^(-77)".

Step  1  :

 1.1     10 = 2•5

(10)^-77 = (2•5)^(-77) = (2)^(-77) • (5)^(-77)

Equation at the end of step  1  :

  5 • ((2)(-77)•(5)(-77))

Step  2  :

Dividing exponents :

 2.1    5¹   divided by   5⁷⁷   = 5^{(1 - 77)} = 5^(-76) = ¹/_5⁷⁶

Final result :

      1                                       
  ————————— = 5.00000 • 10-77 
  (277•576)
