Solution - Power equations

Step  1  :

Equation at the end of step  1  :

            16          
  ((82) -  (—— • 4)) -  3
            22          

Step  2  :

            16
 Simplify   ——
            22

Raising to a Power :

 2.1    2⁴   divided by   2²   = 2^{(4 - 2)} = 2²

Equation at the end of step  2  :

  ((82) -  (4 • 4)) -  3

Step  3  :

 3.1     8 = 23

(8)² = (2³)² = 2⁶

Equation at the end of step  3  :

  (26 -  16) -  3

Step  4  :

Final result :

  45
