this is wierd to write but ill do my best.

Question

12 4 square root 2 (the 4 is on top of the radical if that helps) - 7 4 square root 312 (again the 4 is on top of the radical)

if this is confusing ill try to break it down more.

thank you

Answer 1

first, it is not a square root sign, it is a fourth root sign

12Fourthroot2-7sqrt312
12fourthroot2-7fourthroot(3*13*2*2*2)
I don't see how it can be simplified more

Answer 2

so it would pretty much stay the same?
