Review of Introductory Mathematics RADICALSSimplifyingRadicalsAn expression having radicals is in simplest form when:The index cannot be reduced.The radicand is simplified.No radicals are in the denominator.There are four rules of radicals that will be useful in simplifying them.Rule 1:nanna^{n}aRule 2:nabnanbRule 3:Rule 4: , when n is odd.nanaExamples:10^{2}10326326279393333543( 27)(2)32732332When a radical sign exists in the denominator, it is desirable to remove the radical. This is doneby multiplying both the numerator and denominator by the radical and simplifying.Example:353555355Rev. 0 Page 75 MA-01
