Alright, so I've go this question where I'm to rationalize the numerator. [Grade 10 Level] 1. The problem statement, all variables and given/known data (1+sqrt(2)-sqrt(3))/(sqrt(2)) http://www.myalgebra.com/math_image.aspx?p=SMB02FSMB031+SMB02RSMB032SMB02rSMB03-SMB02RSMB033SMB02rSMB03SMB10SMB02RSMB032SMB02rSMB03SMB02fSMB03?p=74?p=42 [Broken] 2. Relevant equations 3. The attempt at a solution I'm not going to type all of my entire failed attempts. Though, I did try seperating this into two fractions, but I don't think that'd be useful. I also multiplied the numerator and denominator by the numerator's conjugate, I think. Although I'm not sure: (1+sqrt(2)-sqrt(3))/(sqrt(2))*((sqrt(2))+(sqrt(3)))/((sqrt(2))+(sqrt(3))) http://www.myalgebra.com/math_image.aspx?p=SMB02FSMB031+SMB02RSMB032SMB02rSMB03-SMB02RSMB033SMB02rSMB03SMB10SMB02RSMB032SMB02rSMB03SMB02fSMB03*SMB02FSMB03(SMB02RSMB032SMB02rSMB03)+(SMB02RSMB033SMB02rSMB03)SMB10(SMB02RSMB032SMB02rSMB03)+(SMB02RSMB033SMB02rSMB03)SMB02fSMB03?p=164?p=42 [Broken] I think the positive one in the equation is what's causing me to lose.
