A negative exponent in the numerator can always be replaced by a positive exponent in the denominator, and vice versa. In your first example, 12x and z are raised to negative exponents, so you move them to the denominator, getting y / 12xz^-3. Note that when you replace the exponent of -1 with an exponent of 1, you no longer need to write it.

I don't quite understand the question, but here's how you get rid of negative exponents:
Move the monomial to the other side of the fraction and change the exponent's sign from negative to positive.
EG, 3x^(-4) is the same as 3 / x^4
5 / 4x^(-2) is the same as 5x^2 / 4

I can't really tell what your problems are, but the general rule is
x^-m = 1/x^m and 1/x^-m = x^m
In other words, a negative exponent changes the number's or variable's position in a fraction. If a numerator number or variable has a negative exponent, move it to the denominator, and vice versa. Then you can proceed to simplify using other exponent rules.

Okay first thing you can do, is flip some negative integers.. Like if it was 3x+(-7) then you can turn it into 3x-7? I'M IN SEVENTH GRADE ALGEBRA OKAY I DON'T KNOW ALL THIS !!!!!
