Best ResponseYou've already chosen the best response.0for another way, look up "NewtonRaphson" method... long winded but will work out all square roots for you, eg sqrt 3, sqrt 168

Best ResponseYou've already chosen the best response.0guesstimating you know 10^2 = 100, so must be bigger you know 15^5 = 225, so must be smaller, leaves a range of 4 possibilities

Best ResponseYou've already chosen the best response.0Also, you know that it must end with either a three or a seven. And since you know it has to be greater than 10 and less than 15 your only choice is 13
