The domain in terms of are all the values that make the radicand greater than .
To find the square root end point, substitute the value , which is the terminal value in the domain, into .
Replace the variable with in the expression.
Simplify the result.
Raising to any positive power yields .
Rewrite as .
Pull terms out from under the radical, assuming positive real numbers.
The final answer is .
The square root end point is .
