include how u got there please

(12x)^-1yz^-3 there are fraction bars under each line

-4x^3
y^2z^2

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.

1/ 12xy^3

and the others are expressions without negative exponents

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 !!!!!
