ok, I prefer to use x's rather than stars just because it is easier on the eyes.
So: we basically get 4x=x%5E4
subtract 4x from both sides and get 0=x%5E4-4x
Next:factor out an x from x^4 and 4x so: 0=x%28x%5E3-4%29
The statement will be true when either x=0 or (x^3-4)=0
So, how do we know when x^3-4=0???
add 4 to both sides and you get x%5E3=4
take the cubed root of each side and you get x= the cubed root of 4
therefore, the star's value can either be 0 or the cubed root of 4
