You multiply exponents when you raise a variable or a constant to some power.

\n" ); document.write( " $\"%28x%5E2%29%5E3+=+x%5E%282%2A3%29\"$ = $\"x%5E6\"$
\n" ); document.write( " $\"%283%5E2%29%5E3+=+3%5E%282%2A3%29\"$ = $\"3%5E6+=+729\"$ \r
\n" ); document.write( "\n" ); document.write( "Whenever you multiply variables, then you woul add the exponents only if the variables (also called the base) are the same.

\n" ); document.write( " $\"%28x%5E2%29%28x%5E3%29+=+x%5E%282%2B3%29\"$ = $\"x%5E5\"$
\n" ); document.write( " $\"%284%5E3%29%284%5E4%29+=+4%5E%283%2B4%29\"$ = $\"4%5E7+=+16384\"$ \n" ); document.write( "
