Solution - Power equations

Reformatting the input :

Changes made to your input should not affect the solution:

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

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

Step  1  :

 1.1     10 = 2•5

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

Equation at the end of step  1  :

  288
  ——— • ((2)(-7)•(5)(-7))
  100

Step  2  :

            72
 Simplify   ——
            25

Equation at the end of step  2  :

  72
  —— • ((2)(-7)•(5)(-7))
  25

Step  3  :

Multiplying exponents :

 3.1    5²  multiplied by  5⁷   = 5^{(2 + 7)} = 5⁹

Dividing exponents :

 3.2    2³   divided by   2⁷   = 2^{(3 - 7)} = 2^(-4) = ¹/_2⁴

Final result :

     9                                     
  ——————— = 2.88000 • 10-7 
  (59•24)
