You dont need to solve

osanseviero · Answer

Just explain me how to do it (which is the order)

anonymous · Answer

Basically, whenever you have a negative exponent when there's one term over another, then the terms switch places from top to bottom.

anonymous · Answer

First distribute the -4 exponent.

osanseviero · Answer

ok...shouldnt it be first to divide?

anonymous · Answer

I guess you could. Yeah. It would be easier that way. Start inside out.

anonymous · Answer

Just set up a huge fraction to start off.
