Best ResponseYou've already chosen the best response.0to rationalize a sqrt fraction, you multiply your fraction by the botton sqrt: \[\sqrt{3}/\sqrt{28} \times \sqrt{28}/\sqrt{28} = \sqrt{3}*\sqrt{?}\]

Best ResponseYou've already chosen the best response.0I still am not understanding what you mean by square root of 28. there is no square root, right? that is only when two numbers can multiply by each other and equal that number, right?

Best ResponseYou've already chosen the best response.0\[ \sqrt{3}\over \sqrt{28}\] =\[\sqrt{3}\sqrt{28}\over 28\]=\[\sqrt{84\over 28}\]=\[2\sqrt{21}\over28\]\[\sqrt{21}\over14\] You are multiplying both the numerator and denominator to rationalize the denominator and simplifying when possibler.

Best ResponseYou've already chosen the best response.0The number you are using is the radical in the denominator, in this case the square root of 28.
