Perform the indicated operation.

\n" ); document.write( "1) cubed root of 9x squared TIMES cubed root of 3x
\n" ); document.write( "\"CubeRt%289x%5E2%29\" * \"CubeRt%283x%29\"
\n" ); document.write( "can be combined, do the math, and note that 27x^3 is a perfect cube
\n" ); document.write( "\"CubeRt%289x%5E2%2A3x%29\" = \"CubeRt%2827x%5E3%29\" = 3x
