\"log%2810%2C%28sqrt%28x%5E3-9%29%29%29=2\" Start with the given equation. Note: Since you did not specify a base, this means that we're going to use the default base 10.\r

\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"10%5E%282%29=sqrt%28x%5E3-9%29\" Rewrite the equation using the property: \"log%28b%2C%28x%29%29=y\" ====> \"b%5Ey=x\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"100=sqrt%28x%5E3-9%29\" Evaluate \"10%5E%282%29\" to get \"100\"\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"10000=x%5E3-9\" Square both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"10009=x%5E3\" Add 9 to both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"root%283%2C10009%29=x\" Take the cube root of both sides\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So our answer is \"x=root%283%2C10009%29\" which is approximately \"x=21.5508082663667\"
