网考网解析：
The best solution here is to plug in the numbers from the answers until you find the range that works. 21×21=441, 24×24=576, 25×25=625, 27×27=729, 28×28=784, 30×30=900... and we do not need to determine the square of 31 to know that the square root of 800 is between 27 and 31. document.getElementById("warp").style.display="none"; document.getElementById("content").style.display="block"; 查看试题解析出处>>
