Using the rule  = ,
raise 8 to the left side power and set
that equal to 8 raised to the right
side power:

Simplify using the rule above

 = 

Remembering that same rule again,
raise 4 to the left side power and set
that equal to 4 raised to the right
side power: 

 = 
  
Using that rule, raise 4 to the left side 
power and set that equal to 4 raised to 
the right side power: 

Simplify using the same rule:

 = 

Remembering that same rule one final time,
raise 2 to the left side power and set
that equal to 2 raised to the right
side power:

 = 

Simplify using the same rule:
