This one might also be interpreted as.......

[√(6x^3) / √(3x)]  * √(8x^2) =

√(2x^2)   * √(8x^2) =

√(16x^4)  =

4x^2   ......In which case the answer is B.......(I kinda' think A might not be the correct answer because √16 could be simplified further......)

The lack of parenthesis and brackets in some of these questions makes it tough to discern what the intent might be......Parenthesis and brackets aren't just for "show"   !!!!!!

sqrt6x^3 / sqrt3x = sqrt(2x^2)*sqrt(8x^2) = sqrt(16x^4) / A.
