Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-2" was replaced by "^(-2)".

(2): "8.32" was replaced by "(832/100)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  832
  ——— • ((2)(-2)•(5)(-2))
  100

Step  2  :

            208
 Simplify   ———
            25 

Equation at the end of step  2  :

  208
  ——— • ((2)(-2)•(5)(-2))
  25 

Step  3  :

Multiplying exponents :

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

Dividing exponents :

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

Final result :

   52           
  ——— = 0.08320 
  625
