The discussion revolves around rationalizing square roots and simplifying expressions involving square roots, particularly in the context of algebraic manipulation. The original poster presents a complex expression that includes square roots and seeks clarification on the process of rationalization.
There is an ongoing exploration of the original problem, with some participants attempting to clarify the expression and others questioning the assumptions made. A few suggestions for notation improvements and algebraic approaches have been offered, but no consensus has been reached.
Participants note the importance of clear notation, such as using parentheses and standard mathematical symbols, to avoid confusion in the discussion. There is also mention of specific values being plugged into the expression, which may not align with the original problem setup.
If you aren't going to use Latex at least use parentheses to clarify- and "t^2" is clearer than "square t".afcwestwarrior said:9-t/3-squared t x 3 + square t/3+square t
i get on top 27+9square t -3t-t square t/9-3square t- 3 square t + t
i forgot what happens when u rationa,ize sqaure roots like this
[itex]3\sqrt{5}+ 3\sqrt{7}[/itex]? About the only thing you can do is factor out the three: [itex]3(\sqrt{5}+ \sqrt{7})[/itex]. There is no way to "add square roots" of different numbers.afcwestwarrior said:i need help man, anyone know how to add square roots such as 3 square root 5 + 3 square root 7,
Plug 9 into what? What are you talking about?afcwestwarrior said:this doesn't make sense because whenever i plug in the 9 i get 3 and the answer is 6, it doesn't make sense.
