Best ResponseYou've already chosen the best response.0Nah, you really only have to remember that when you have even roots, you can't have negative numbers inside.

Best ResponseYou've already chosen the best response.0Y= ^4root(5x2) Can you clean that up? It makes no sense as written.

Best ResponseYou've already chosen the best response.0its the quad root of 5x2

Best ResponseYou've already chosen the best response.0OK. If you take an even root of an expression, the expression has to be greater than or = 0: the even root of a negative number is imaginary. (Odd roots of negatives are fine.) So, as wio said, figure out where the radicand (5x  2) is > or = 0.
