You can put this solution on YOUR website!
One way or another you will need to use a calculator (or a table of logarithms) to figure this out.

\n" ); document.write( "Here's a calculator-based procedure you can follow:

Figure out the base of the logarithm involved. You do not mention a base. If there is no mention of a base, or \"ln\" or \"natural logarithm\", then the base is probably 10. If \"ln\" or \"natural logarithm\" are mentioned, then the base is \"e\". (If your calculator does not have a key for \"e\", use 2.7182818284590451 or a rounded off version of this number.
Figure out how to exponentiate (raise a number to a power) on your calculator. Different calculators use different keys for this so it is difficult for me to provide specific help. Often the key is \"^\" or \" $\"x%5Ey\"$ \". You enter the base, then press if exponentiate key, then enter the exponent and finally press the \"=\" or \"Enter\" key. Try it out on $\"3%5E4\"$ and see if you get the correct answer: 81.
Unless your calculator supports parenthesized expressions and you know how to enter a parenthesized expression, subtract the two numbers of the 2nd and third logarithms above in advance.
Now you just raise the base (from step #1) to the logarithm power, one at a time.
