solve these equations.
\n" ); document.write( "a. \"3sqrt%28x-2%29\" = -5
\n" ); document.write( "Cube both sides
\n" ); document.write( "x - 2 = -5^3
\n" ); document.write( "x - 2 = -125
\n" ); document.write( "x = -125 + 2
\n" ); document.write( "x = -123
\n" ); document.write( "Check this in the original equation
\n" ); document.write( "\"3sqrt%28-123-2%29\" =
\n" ); document.write( "\"3sqrt%28-125%29\" = -5, (the cube root of -125 is -5)
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "b. \"x%5E%281%2F3%29-+2+=+0\"
\n" ); document.write( "\"x%5E%281%2F3%29+=+2\"
\n" ); document.write( "cube both sides
\n" ); document.write( "x = \"2%5E3\"
\n" ); document.write( "x = 8
\n" ); document.write( "Check in original equation
\n" ); document.write( "\"8%5E%281%2F3%29-+2+=+0\"
\n" ); document.write( "find the cube root of 8
\n" ); document.write( "2 - 2 = 0
\n" ); document.write( "
\n" );
