Problem 6 Got It? Suppose you were going to rationalize the denominator of the expression.
Would you simplify √8 before or after rationalizing? Explain your answer.
Before rationalizing; radicals should ALWAYS be simplified first when rationalizing a denominator.
After rationalizing; multiplying the numerator by the conjugate of the denominator is more convenient if √8 is not yet simplified.
