Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-7" was replaced by "^(-7)".

(2): "7.6" was replaced by "(76/10)".

Step  1  :

 1.1     10 = 2•5

(10)^-7 = (2•5)^(-7) = (2)^(-7) • (5)^(-7)

Equation at the end of step  1  :

  76
  —— • ((2)(-7)•(5)(-7))
  10

Step  2  :

            38
 Simplify   ——
            5 

Equation at the end of step  2  :

  38
  —— • ((2)(-7)•(5)(-7))
  5 

Step  3  :

Multiplying exponents :

 3.1    5¹  multiplied by  5⁷   = 5^{(1 + 7)} = 5⁸

Dividing exponents :

 3.2    2¹   divided by   2⁷   = 2^{(1 - 7)} = 2^(-6) = ¹/_2⁶

Final result :

     19                                    
  ——————— = 7.60000 • 10-7 
  (58•26)
