I am not sure I understand the problem. I will assume this is a fourth root of a square root, since B is not the answer.
\n" ); document.write( "The first square root is 4x^2*y^2*sqrt(y),
\n" ); document.write( "The second square root is 9y^3*sqrt(3y)
\n" ); document.write( "These can be multiplied to get 36x^2*y^6*sqrt (3)
\n" ); document.write( "---------------------------------------------------------'
\n" ); document.write( "The fourth root of this must only have a y out front and none of the choices have this.
\n" ); document.write( "Furthermore, the constant is a minimum of 2 *fourth root of (3), and no choices have this.
\n" ); document.write( "-------------------------------
\n" ); document.write( "Just taking the square root of the above gets me 6xy^3 fourth root of 3, which is closest to D, but it is not D.
\n" ); document.write( "If there is a fourth root of all of this, y should be cubed, since there are y^12 under the fourth root.
\n" ); document.write( "--------------------------------
\n" ); document.write( "Therefore, I am misreading the notation of the problem or of the answer choices, and I am unclear as to what is a fourth root and what is a square root here.
\n" ); document.write( "-----------------------------------------------------
\n" ); document.write( "
\n" );
