Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-5" was replaced by "^(-5)".

(2): "6.875" was replaced by "(6875/1000)".

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  6875
  ———— • ((2)(-5)•(5)(-5))
  1000

Step  2  :

            55
 Simplify   ——
            8 

Equation at the end of step  2  :

  55
  —— • ((2)(-5)•(5)(-5))
  8 

Step  3  :

Multiplying exponents :

 3.1    2³  multiplied by  2⁵   = 2^{(3 + 5)} = 2⁸

Dividing exponents :

 3.2    5¹   divided by   5⁵   = 5^{(1 - 5)} = 5^(-4) = ¹/_5⁴

Final result :

     11             
  ——————— = 0.00007 
  (28•54)
