Solution - Simplification or other simple results

Step  1  :

 1.1     18 = 2•32

(18)⁴ = (2•3²)⁴ = 2⁴ • 3⁸

Equation at the end of step  1  :

  (1819) • (24•38)

Step  2  :

 2.1     18 = 2•32

(18)¹⁹ = (2•3²)¹⁹ = 2¹⁹ • 3³⁸

Equation at the end of step  2  :

  (219•338) • (24•38)

Step  3  :

Multiplying exponents :

 3.1    2¹⁹  multiplied by  2⁴   = 2^{(19 + 4)} = 2²³

Multiplying exponents :

 3.2    3³⁸  multiplied by  3⁸   = 3^{(38 + 8)} = 3⁴⁶

Final result :

  (223•346)
