Best ResponseYou've already chosen the best response.0what kind of square roots are you specifically talking about? is it surds or what?

Best ResponseYou've already chosen the best response.0i dont even know what that is, its like a regular one, you have to find a perfect square first to find it.

Best ResponseYou've already chosen the best response.0(radical sign)169, i know the answer is 13 but i have to simplfiy the square root

Best ResponseYou've already chosen the best response.0This is what my book says: Simplifiy each square root. \[\sqrt{169}\]

Best ResponseYou've already chosen the best response.0simplifying just makes sense when you have expression with variables, e.g sqrt( cos^2(x)+sin^2(x)+1) , otherwise you jusr try to evaluate the square root of the numer, like in thes case, if the answer is not that easy, you could try thongs like this: sqrt(20) = sqrt(5*4) = 2*sqrt(5)

Best ResponseYou've already chosen the best response.0how did you do that pentop?

Best ResponseYou've already chosen the best response.0what i mean is that simplifying means dealing with variables not with numbers, however, \[\sqrt{121}=11\]

Best ResponseYou've already chosen the best response.0sorry, I meant 11squared =121..

Best ResponseYou've already chosen the best response.0i know that it is 11 but i have to simplifiy it, im so confused. i know how to solve them, i cant simplifiy with perfect squares though

anonymous

Best ResponseYou've already chosen the best response.0simplifying the square root simply means doing the operation of taking the square or making sure that there are no perfect squares under the radical sign. so with your problem, 13 is the simplification of root 169.

Best ResponseYou've already chosen the best response.0The only way I can think of to show it is to factor what is under the radical into 11^2 and then the square root of something squared is just that, in this case 11

Best ResponseYou've already chosen the best response.0\[\sqrt{121}\] = \[\sqrt{11 x 11}\] = 11
