Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-4" was replaced by "^(-4)".

(2): "4." was replaced by "(4/1)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  4
  — • ((2)(-4)•(5)(-4))
  1

Step  2  :

            4
 Simplify   —
            1

Equation at the end of step  2  :

  4 • ((2)(-4)•(5)(-4))

Step  3  :

Dividing exponents :

 3.1    2²   divided by   2⁴   = 2^{(2 - 4)} = 2^(-2) = ¹/_2²

Final result :

    1
