Solution - Simplification or other simple results

Step  1  :

 1.1     72 = 23•32

(72)² = (2³•3²)² = 2⁶ • 3⁴

Equation at the end of step  1  :

  ((723) +  (26•34)) +  18

Step  2  :

 2.1     72 = 23•32

(72)³ = (2³•3²)³ = 2⁹ • 3⁶

Equation at the end of step  2  :

  ((29•36) +  (26•34)) +  18

Step  3  :

Step  4  :

Pulling out like terms :

 4.1     Pull out like factors :

   2⁹ • 3⁶ + 5202  =   18 • (4 + 289) 

Final result :

  18 • (4 + 289)
