How would you go about rationalising something where the denominator is all in brackets like:
(2 + √3)^2
expand that out and u will an answer in the form a+broot(3) and then carry on as u normally would by multiplying top and bottom by a-broot(3). find a and b by urself
ignore my previous post as i read it wrong. expand root 2 + root 3 squared and see whatu get. u shud get something in the form a+broot(6). after that rationalise normally
