for another way, look up "NewtonRaphson" method... long winded but will work out all square roots for you, eg sqrt 3, sqrt 168

guesstimating you know 10^2 = 100, so must be bigger you know 15^5 = 225, so must be smaller, leaves a range of 4 possibilities

Also, 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
