The Quotient Rule for Radicals 7.42

Simplify  By taking roots of numerators & denominators 7.43

Simplify  By combining and simplifying under the radical 7.44

A Radical Expression is Simplified When: 1.Each factor in the radicand is to a power less than the index of the radical 2.The radicand contains no fractions or negative numbers 3.No radicals appear in the denominator of a fraction 7.45

Rationalize the Denominator  By simplifying inside the radical  Think about what is needed on the bottom! 7.46

Rationalize the Denominator  By simplifying outside the radical 7.47

Rationalize the Numerator ?  Required only for Calculus, but learn the way: 7.48
