A perfect square is a number that can be expressed as theproduct of two equal integers. Examplesof perfect squares 9 9 is a perfect square because it can be expressed as 3 * 3 (the product of two equal integers). 16 16 is a perfect square because it can be expressed as 4 * 4 (t...
解析 BA whole number is a perfect square if it is the product of two equal whole numbers. Thus, 1*1 and 2*2 and 3*3 and 4*4 are perfect squares. Continue until the product is bigger than 1000:30*30=900; 31*31=961; 32*32=1024 (too big). ...
