Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

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

(2): "5.6" was replaced by "(56/10)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  56
  —— • ((2)(-4)•(5)(-4))
  10

Step  2  :

            28
 Simplify   ——
            5 

Equation at the end of step  2  :

  28
  —— • ((2)(-4)•(5)(-4))
  5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5⁴   = 5^{(1 + 4)} = 5⁵

Dividing exponents :

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

Final result :

     7              
  ——————— = 0.00056 
  (55•22)
