Algebra/Trig ReviewRadicalsEvaluate the following.1. 3125SolutionIn order to evaluate radicals all that you need to remember isnny = x is equivalent to x=yIn other words, when evaluating n x we are looking for the value, y, that we raise tothe n to get x. So, for this problem we’ve got the following.3 3125 = 5 because 5 = 1252. 6643.5Solution664 = 2 because62 = 64− 243Solution5− 243 =−3 because − 3 =− 2434. 2100( ) 5Solution2100 = 100 = 102Remember that x = x45. − 16Solution4− 16 = n/aTechnically, the answer to this problem is a complex number, but in most calculusclasses, including mine, complex numbers are not dealt with. There is also the factthat it’s beyond the scope of this review to go into the details of getting a complexanswer to this problem.Convert each of the following to exponential form.6. 7xSolution© 2006 Paul Dawkins 8http://tutorial.math.lamar.edu/terms.aspx
