Best ResponseYou've already chosen the best response.0ok, to do this you'd *like* to find a perfect square that is a factor of 50

Best ResponseYou've already chosen the best response.0now by the property of radicals  we know that the square root of two number multipled: e.g. \[\sqrt{a*b} = \sqrt{a} * \sqrt{?}\]

Best ResponseYou've already chosen the best response.0so \[\sqrt{50} = \sqrt{25 * 2} = \sqrt{25} * \sqrt{2} = 5 * \sqrt{?}\]

Best ResponseYou've already chosen the best response.0see dont listen to sandra and galf of the work is done follow this suppose that you have to find sqrt of 50 look for nearest perfect sqrt so aqrt of following numbers are 1 =1 4=2 9=3 25=5 36=6 49=7 64=8 so the sqrt of five lies between 7 and 8 that is it has to be something like 7point something got it
