Solution - Nonlinear equations

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (3x22 • x) -  8  = 0 
 Step  2  :

Equation at the end of step  2  :

  3x23 - 8  = 0 

Step  3  :

Solving a Single Variable Equation :

 3.1      Solve  :    3x²³-8 = 0 

 Add  8  to both sides of the equation : 
                      3x²³ = 8
Divide both sides of the equation by 3:
                     x²³ = 8/3 = 2.667
                     x  =  23rd root of (8/3) 

 The equation has one real solution
This solution is  x = 23rd root of ( 2.667) = 1.04357
