A “simple square” is any integer greater than 1 that has only three positive integer factors—itself,its square root, and 1.
\n" ); document.write( "Which of the following is a simple square?
\n" ); document.write( "A. 121 B. 100 C. 81 D. 64 E. 33 \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "factor each of the choices
\n" ); document.write( "121 = 11^2 = 1 * 121 = 1 * 11 * 11 (3 positive integer factors)
\n" ); document.write( "100 = 10^2 = 2^2 * 5^2 = 1 * 4 * 25 = 1 * 2 * 2 * 5 * 5
\n" ); document.write( "81 = 9^2 = 1 * 3 * 27 = 1 * 3 * 3 * 3 * 3
\n" ); document.write( "64 = 8^2 = 2^2 * 4^2 = 1 * 8 * 8 = 1 * 2 * 2 * 2 * 2 * 2 * 2
\n" ); document.write( "33 = 1 * 3 * 11
\n" ); document.write( "33 is not a product of a whole number times itself like the other choices\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the answer is A. 121 \n" ); document.write( "

\n" );
