Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-8" was replaced by "^(-8)".

(2): "2.88" was replaced by "(288/100)".

Step  1  :

 1.1     10 = 2•5

(10)^-8 = (2•5)^(-8) = (2)^(-8) • (5)^(-8)

Equation at the end of step  1  :

  288
  ——— • ((2)(-8)•(5)(-8))
  100

Step  2  :

            72
 Simplify   ——
            25

Equation at the end of step  2  :

  72
  —— • ((2)(-8)•(5)(-8))
  25

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁸   = 5^{(2 + 8)} = 5¹⁰

Dividing exponents :

 3.2    2³   divided by   2⁸   = 2^{(3 - 8)} = 2^(-5) = ¹/_2⁵

Final result :

      9                                     
  ———————— = 2.88000 • 10-8 
  (510•25)
