Solution - Linear equations with one unknown

Reformatting the input :

Changes made to your input should not affect the solution:

 (1): "b7"   was replaced by   "b^7". 

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

                     4*b^28*b^7-(4)=0 

Step by step solution :

Step  1  :

Equation at the end of step  1  :

  (22b28 • b7) -  4  = 0 
 Step  2  :
 Step  3  :

Pulling out like terms :

 3.1     Pull out like factors :

   4b³⁵ - 4  =   4 • (b³⁵ - 1) 

Equation at the end of step  3  :

  4 • (b35 - 1)  = 0 

Step  4  :

Equations which are never true :

 4.1      Solve :    4   =  0

This equation has no solution.
A a non-zero constant never equals zero.

Solving a Single Variable Equation :

 4.2      Solve  :    b³⁵-1 = 0 

 Add  1  to both sides of the equation : 
                      b³⁵ = 1
                     b  =  35th root of (1) 

 The equation has one real solution
This solution is  b =
