Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

(1): "^-12" was replaced by "^(-12)".

Step  1  :

Multiplying exponential expressions :

 1.1    x² multiplied by x^(-12) = x^{(2 + (-12))} = x^(-10) = ¹/_x¹⁰

Final result :

  x(-10)
