Question 331106: Rationalize the denominator. Assume that all expressions under radicals represent positive numbers.
-√(25/12)
Need to know if I am on hte right track in solving this problem
=-√25/√12
= - (√25∙√12)/(√12∙√12)
= - √300/12
= - (5√60)/12

You were doing great until you got a little balled up trying to simplify

Go back one step:



Do the denominator but leave the numerator alone for the moment:



Now, , so:



And since , we can write:



and we're done.
