Solution - Power equations

Step  1  :

Equation at the end of step  1  :

         5
  0 -  ((— • 225) • 210)
         9

Step  2  :

            5
 Simplify   —
            9

Equation at the end of step  2  :

         5
  0 -  ((— • 225) • 210)
         9

Step  3  :

Equation at the end of step  3  :

        (5•225)
  0 -  (——————— • 210)
           9   

Step  4  :

Multiplying exponents :

 4.1    5¹  multiplied by  5¹   = 5^{(1 + 1)} = 5²

Multiplying exponents :

 4.2    2²⁵  multiplied by  2¹   = 2^{(25 + 1)} = 2²⁶

Dividing exponents :

 4.3    3¹   divided by   3²   = 3^{(1 - 2)} = 3^(-1) = ¹/_3¹ = ¹/₃

Equation at the end of step  4  :

       (52•226•7) 
  0 -  ——————————
           3     

Step  5  :

Final result :

  ( -52•226•7)                                   
  ———————————— = -3.91468 • 109
