Answer» 60Step-by-step explanation:We NEED to find a perfect square close to 27285 and smaller than it.Lets try to guess the NUMBER. From the first look 272 is close to 16^2=256 and 17^2=289. So the number should be between 160^2 and 170^2.See what is 165^2. It is 272225 and it is smaller than 27285. Try 166^2. It's 27556, is greater than given number. So the perfect square we are LOOKING is 272225.27285-27225=60 is the least number to be subtracted.
