Hello,
To evaluate the expression (x-2)^1/2 the next steps listed are x^(-2)(1/2)
then x^-1 and finally 1/x. I am fine with the final two steps.
Please help me see how or what rules are used to go from the first to second step. Is this just a basic rules I am forgetting?
So in summary how does (x-2)^1/2 become x^(-2)(1/2)
Thank you.
... by typo!
1. I assumed that there was a typo in the original term and that actually was meant
2. If you re-arrange the given term
you can see that
has only one real solution at
To answer your question So in summary how does (x-2)^1/2 become x^(-2)(1/2): Only once - and in all other cases this transformation is wrong.
