Question 1
1.
Review Lesson 6-1: Simplify the radical expression. Use absolute value symbols when needed.
Always ensure that simplified radical expressions are equivalent to the original. This should be true regardless of whether the values of the variables are positive or negative.
It may be helpful to remember that \sqrt{x^{2}}\neq x for negative values of x. This is due to the even power of x. Adding an absolute value resolves that issue: \sqrt{x^{2}}=|x|.

A real number can have a denominator equal to 0.
Multiplying both the numerator and denominator by the same nonzero number results in an equivalent fraction.
All mathematical expressions can be written as an equivalent expression with a denominator of 1.
The expression above a fraction bar is called the denominator.
