Solution - Simplification or other simple results

Step  1  :

 1.1     9 = 32

(9)³ = (3²)³ = 3⁶

Equation at the end of step  1  :

  ((98) • (91)) • 36

Step  2  :

 2.1     9 = 32

(9)¹ = (3²)¹ = 3²

Equation at the end of step  2  :

  ((98) • 32) • 36

Step  3  :

 3.1     9 = 32

(9)⁸ = (3²)⁸ = 3¹⁶

Equation at the end of step  3  :

  (316 • 32) • 36
 Step  4  :

Multiplying exponents :

 4.1    3¹⁸  multiplied by  3⁶   = 3^{(18 + 6)} = 3²⁴

Final result :

  324
