This week I learned that coefficients have an invincible exponent

Also when reciprocating negative exponents from the variable, the coefficient stays because it has a positive exponent, only the variable with the negative exponent moves to become a positive. But if you move the coefficient that has a positive exponent then the coefficient becomes negative.

 

Here there is a negative exponent right beside the coefficient, so the coefficient stays but the variable moves because it is negative. On the bottom it is the same but there is a bracket, the bracket tells me that the 4 is connected to the negative exponent, so both of them moves up even though the coefficient is positive.

 

Here I just reciprocated the negatives.

 

 Lastly, I simplify.
