Algebra: Chapter 11-5
Dividing and Simplifying
The sqrt of quotients is pretty simple. You can combine or break apart quotient sqrts to you liking. Try to find perfect squares and make sure that all the factors are simplified. Remember too, to “rationalize the denominator”. Make sure that NO radical appears in the denominator. If you have one, multiply the numerator and denominator by 1 (the sqrt of the denominator) to make it disappear. The sqrt(a) * sqrt(a) = sqrt(a^2) = a! See this link from purplemath.com.
