It depends if your book/teacher wants the exact answer or an approximate
\n" ); document.write( "1. To find the approximate answer simply plug it into a calculator
\n" ); document.write( "- \"sqrt%28128%29+=+11.3137\"
\n" ); document.write( "2. To find the exact answer is a little more complicated
\n" ); document.write( "a. First see if 128 is divisible by any perfect squares (eg. 4,9,16,25... etc)
\n" ); document.write( "- \"sqrt%28128%29\"
\n" ); document.write( "b. Since it is divisible by 64 then simplify
\n" ); document.write( "- \"sqrt%28%2864%29%2A%282%29%29\"
\n" ); document.write( "- \"sqrt%2864%29%2Asqrt%282%29\"
\n" ); document.write( "- \"8%2Asqrt%282%29\"
\n" ); document.write( "c. And there's your final answer
\n" ); document.write( "- \"8sqrt%282%29\"
\n" ); document.write( "3. So depending on what answer your book/teacher wants, your answers will be
\n" ); document.write( "- \"11.3137\" or \"8sqrt%282%29\"
\n" ); document.write( "
\n" );
