anonymous · Answer

whenever you see a negative exponent, you can swap its position from the numerator to the denominator (or from the denominator to the numerator) and change the sign of the exponent from negative to positive.

anonymous · Answer

so it's x^4 over 5?

anonymous · Answer

close, but you moved the 5 for some reason.  keep the 5 where it was originally.  the negative exponent was only acting on x.

anonymous · Answer

oh.. so its 5 over x^4?

anonymous · Answer

sorry im horrible at math.... lol

anonymous · Answer

not quite.

if you have

5/ x^(-4), then bring the x^(-4) to the numerator, and change the exponent from negative to positive

you will end up with 5x^4
