You can put this solution on YOUR website!
Not many people would or be expected to perform basic elementary arithmetic to compute \"16%5E18\". What you are missing is logarithmic and exponential functions, and computers.\r

\n" ); document.write( "\n" ); document.write( "You can also make use of laws of exponents.\r
\n" ); document.write( "\n" ); document.write( "\"16=2%5E4\", a basic commonly known fact.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"16%5E18=%282%5E%284%29%29%5E18\"

\n" ); document.write( "\n" ); document.write( "But one reason it would not be done by hand is because the product will have too many digits causing long labor and likelihood of mistakes.\r

\n" ); document.write( "\n" ); document.write( "If this were to be a test question, you would either use a portable hand calculator or use a table of logarithms. A computation like this will NOT be done to the nearest whole value.
