You multiply $\"%28x%5E5%29%2A%28x%5E7%29\"$ by just adding the two exponents to get $\"x%5E12\"$ .
\n" ); document.write( ".
\n" ); document.write( "Think about it. By the definition of exponents:
\n" ); document.write( ".
\n" ); document.write( " $\"x%5E5+=+x%2Ax%2Ax%2Ax%2Ax\"$ and
\n" ); document.write( " $\"x%5E7+=+x%2Ax%2Ax%2Ax%2Ax%2Ax%2Ax\"$
\n" ); document.write( ".
\n" ); document.write( "When you multiply the right sides of these two equations the problem becomes:
\n" ); document.write( ".
\n" ); document.write( " $\"%28x%2Ax%2Ax%2Ax%2Ax%29%2A%28x%2Ax%2Ax%2Ax%2Ax%2Ax%2Ax%29\"$
\n" ); document.write( ".
\n" ); document.write( "so you end up with 12 x's all multiplied together which is, by definition, $\"x%5E12\"$ \r
\n" ); document.write( "\n" ); document.write( "Hope this helps you understand why the exponent is 12. \n" ); document.write( "
