You can put this solution on YOUR website!
you could use logarithms, but then you'd need a table or calculator (or a slide rule?)\r

\n" ); document.write( "\n" ); document.write( " $\"4%5E2=16\"$ and $\"4%5E3=64\"$ so $\"%284%5E2%29%5Ex=4%5E3\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "using rules for exponents ... 2x=3\r
