20,000 is 2x10^4.\r
\n" ); document.write( "\n" ); document.write( "If we raise this number to the power 4, we have $\"%282x10%5E4%29%5E4\"$ . Now the beauty of scientific notation is that we can split the numbers and the powers and work on them separately, as $\"2%5E4\"$ x $\"%2810%5E4%29%5E4\"$ .\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We then get 16 x $\"10%5E16\"$ which is \"corrected\" back into scientific notation as $\"1.6x10%5E17\"$ .\r
