Using a calculator one will get 10.583.\r \n" ); document.write( "\n" ); document.write( "One could estimate this though:\r \n" ); document.write( "\n" ); document.write( "sqrt(63) is going to be just slightly under 8 [sqrt(64)]. Let's call it 7.9\r \n" ); document.write( "\n" ); document.write( "sqrt(7) is going to be under 3 [sqrt(9)], but moreso than what sqrt(63) was to sqrt(64) Let's call it 2.6 maybe 2.7.\r \n" ); document.write( "\n" ); document.write( "7.9 + 2.6 = 10.5 \n" ); document.write( "7.9 + 2.7 = 10.6 \r \n" ); document.write( "\n" ); document.write( "So it's between 10.5 and 10.6 ... not a bad estimate right?\r \n" ); document.write( "\n" ); document.write( "I hope this helped.\r \n" ); document.write( "\n" ); document.write( "If you have more questions, or this didn't help, please e-mail me at onlyyourmathtutor@yahoo.com. \n" ); document.write( " |
