The log function, for base 10, gives you a number in the form of
\n" ); document.write( " $\"y=10%5Ex\"$ .
\n" ); document.write( "In other words, for y=100, the log(y)=2, since $\"y=10%5E2=100\"$ .
\n" ); document.write( "Logarithms help because large numbers can be handled as small numbers.
\n" ); document.write( "Instead of using one million (1,000,000), I use log(1,000,000)=log(10^6)=6.
\n" ); document.write( "So what number is it when log(y)=3, then $\"y=10%5E3=1000\"$
\n" ); document.write( "a.) $\"y=10%5E3=1000\"$
\n" ); document.write( "b.)log (5)=y, what number do I need so that $\"10%5Ey=5\"$ .
\n" ); document.write( "You can use a calculator, log tables, etc. to find the value.
\n" ); document.write( "It's greater than 0, since $\"10%5E0=1\"$ and less than 1 since $\"10%5E1=10\"$ .
\n" ); document.write( "y=0.699.
\n" ); document.write( "c.)Natural log is similar to log except the base is different (e vs. 10).
\n" ); document.write( "The natural log function, for base e, gives you a number in the form of
\n" ); document.write( " $\"y=e%5Ex\"$ .
\n" ); document.write( "\"e\" is a special number in mathematics, equal to approximately 2.71828.
\n" ); document.write( "Similar to log function above, if ln(b)=2, then $\"b=e%5E2\"$ and
\n" ); document.write( "b= 7.388 \n" ); document.write( "
