The book claims the method for the factorization is:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]x^n - c^n = (x^\frac{n}{2} - c^\frac{n}{2})(x^\frac{n}{2} + c^\frac{n}{2})[/tex]

However, one example uses this:

[tex]x^6 - \frac{1}{64} = x^6 - (\frac{1}{2})^6 = (x^3 - \frac{1}{2})(x^3 + \frac{1}{2})[/tex]

My question is, why isn't 1/2 raised the 3rd power like the method tells you to do?

Any information would be greatly appreciated!
