Use factoring to solve the equation for real values of the variables
z^3/2 - 2^1/2 = 0
I think i'm making it harder then it realy is please help

Hi again civiliam,
We have . Now this leads to . Notice that to get we need to raise to the power of since we know that . Hence raising both sides of the equation to the power yields .
Hope this helps.
This is what I would do:
sorry why 2/3?

ahh I c thank you much!
so i wrote the problem out wrong would I still work it out the same way if the 2^1/2 was z^1/2?
z^3/2 - z^1/2 = 0
Now you can factor out .
Beginning with :
z = 0 or 1.
So the problem changes significantly.
wow that was simple odd how minor changes to a problem can throw me off so easily thanks again
