  (1): "x9"   was replaced by   "x^9". 
Step by step solution :
Step 1 :
Equation at the end of step 1 :
  22x212 • x9  = 0 
Step 2 :
Multiplying exponential expressions :
2.1 x212 multiplied by x9 = x(212 + 9) = x221
Equation at the end of step 2 :
  22x221  = 0 
Step 3 :
Solving a Single Variable Equation :
 3.1      Solve  :    22x221 = 0 
 Divide both sides of the equation by 4:
                     22x221 = 0 
                      22x  =  221st root of (0) 
 Any root of zero is zero. This equation has one solution which is  22x = 0
