Step  1  :

 1.1     10 = 2•5

(10)^-4 = (2•5)^(-4) = (2)^(-4) • (5)^(-4)

Equation at the end of step  1  :

   4          25
  (— • 10) • (—— • ((2)(-4)•(5)(-4)))
   1          10

Step  2  :

            5
 Simplify   —
            2

Equation at the end of step  2  :

   4          5
  (— • 10) • (— • ((2)(-4)•(5)(-4)))
   1          2

Step  3  :

Multiplying exponents :

 3.1    2¹  multiplied by  2⁴   = 2^{(1 + 4)} = 2⁵

Dividing exponents :

 3.2    5¹   divided by   5⁴   = 5^{(1 - 4)} = 5^(-3) = ¹/_5³

Equation at the end of step  3  :

   4           1 
  (— • 10) • ————
   1         4000

Step  4  :

            4
 Simplify   —
            1

Equation at the end of step  4  :

               1 
  (4 • 10) • ————
             4000

Step  5  :

Final result :

   1            
  ——— = 0.01000
