Best ResponseYou've already chosen the best response.0the conjugate is where you change the sign of the radical in the denominator and multiply by it to get rid of the square root in the denominator. Your denominator is 9√5, so the conjugate is 9+√5. So to solve your problem you need to simplify this dw:1434336787389:dw

Best ResponseYou've already chosen the best response.1the first part of the denominator is right... second part... no because when we are multiply square roots it's just that number

Best ResponseYou've already chosen the best response.1\[(9\sqrt{5})(9+\sqrt{5})\] is your denominator .. use foil.. the O and I cancels out
