Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-2" was replaced by "^(-2)".

Step  1  :

 1.1     12 = 22•3

(12)^-2 = (2²•3)^(-2) = (2)^(-4) • (3)^(-2)

Equation at the end of step  1  :

Step  2  :

 2.1     12 = 22•3

(12)¹⁸ = (2²•3)¹⁸ = 2³⁶ • 3¹⁸

Equation at the end of step  2  :

Step  3  :

                           1   
 Divide  (236•318)  by  ———————
                        (24•32)

Multiplying exponents :

 3.1    2³⁶  multiplied by  2⁴   = 2^{(36 + 4)} = 2⁴⁰

Multiplying exponents :

 3.2    3¹⁸  multiplied by  3²   = 3^{(18 + 2)} = 3²⁰

Final result :

  (240•320)
