Solution - Simplification or other simple results

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "g2"   was replaced by   "g^2". 

Step  1  :

Multiplying exponential expressions :

 1.1    g¹ multiplied by g² = g^{(1 + 2)} = g³

Equation at the end of step  1  :

  3g3 • g

Step  2  :

Multiplying exponential expressions :

 2.1    g³ multiplied by g¹ = g^{(3 + 1)} = g⁴

Final result :

  3g4
