Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  (10-4) • ((2)(-4)•(5)(-4))

Step  2  :

 2.1     10 = 2•5

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

Equation at the end of step  2  :

  ((2)(-4)•(5)(-4)) • ((2)(-4)•(5)(-4))

Step  3  :

Multiplying exponents :

 3.1    2⁴  multiplied by  2⁴   = 2^{(4 + 4)} = 2⁸

Multiplying exponents :

 3.2    5⁴  multiplied by  5⁴   = 5^{(4 + 4)} = 5⁸

Final result :

     1
