Hey there :)



When you take x⁴ from the denominator to the numerator, you get x⁻⁴
Therefore, first option: is one correct expression

When you exchange the numerator and denominator, you will have negative powers on them. Such as when you take 6 to the numerator you will have 6⁻¹ and 5 to the denominator is 5⁻¹
So, second option : is another right expression.
