Solution - Simplification or other simple results

Step  1  :

 1.1     12 = 22•3

(12)⁷ = (2²•3)⁷ = 2¹⁴ • 3⁷

Equation at the end of step  1  :

  (122) • (214•37)

Step  2  :

 2.1     12 = 22•3

(12)² = (2²•3)² = 2⁴ • 3²

Equation at the end of step  2  :

  (24•32) • (214•37)

Step  3  :

Multiplying exponents :

 3.1    2⁴  multiplied by  2¹⁴   = 2^{(4 + 14)} = 2¹⁸

Multiplying exponents :

 3.2    3²  multiplied by  3⁷   = 3^{(2 + 7)} = 3⁹

Final result :

  (218•39)
