Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-9" was replaced by "^(-9)".

(2): "2.4" was replaced by "(24/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-9 = (2•5)^(-9) = (2)^(-9) • (5)^(-9)

Equation at the end of step  1  :

  24
  —— • ((2)(-9)•(5)(-9))
  10

Step  2  :

            12
 Simplify   ——
            5 

Equation at the end of step  2  :

  12
  —— • ((2)(-9)•(5)(-9))
  5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5⁹   = 5^{(1 + 9)} = 5¹⁰

Dividing exponents :

 3.2    2²   divided by   2⁹   = 2^{(2 - 9)} = 2^(-7) = ¹/_2⁷

Final result :

      3
