You can put this solution on YOUR website!
$\"log%2810000%29+=+y\"$
\n" ); document.write( ".
\n" ); document.write( "On most scientific calculators ($10 variety) you would just enter 10,000 and press the \"log\" key
\n" ); document.write( "to get the answer of 4.
\n" ); document.write( ".
\n" ); document.write( "This problem you can probably work in your head. Talk yourself through the problem this
\n" ); document.write( "way:
\n" ); document.write( ".
\n" ); document.write( "The base is 10 so what exponent (call it y) do I have to raise 10 to in order to get 10,000?
\n" ); document.write( ".
\n" ); document.write( "you know that $\"10%5E1+=+10\"$ and $\"10%5E2+=+100\"$ and you probably know that $\"10%5E3+=+1000\"$
\n" ); document.write( "so you can probably quickly figure out that $\"10%5E4+=+10000\"$ . From this you can see that the
\n" ); document.write( "exponent to make 10,000 from 10 is 4 and this is exactly what your calculator is telling you.
\n" ); document.write( ".
\n" ); document.write( "If you have a graphing calculator, you will need to do this a different way. Read your
