Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "4.32" was replaced by "(432/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  432
  ——— • ((2)(-4)•(5)(-4))
  100

Step  2  :

            108
 Simplify   ———
            25 

Equation at the end of step  2  :

  108
  ——— • ((2)(-4)•(5)(-4))
  25 

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁴   = 5^{(2 + 4)} = 5⁶

Dividing exponents :

 3.2    2²   divided by   2⁴   = 2^{(2 - 4)} = 2^(-2) = ¹/_2²

Final result :

     27             
  ——————— = 0.00043 
  (56•22)
