Question

When 27x^2z/-3x^2z^4 is completely simplified, the exponent on the variable z is

Answer 1

ignoring everything but the z's (because we can) we're left with
`(z)/( z^(4) )` , which simplifies to
`z^(-3)` , so -3

Answer 2

`-9z^(-3)` that is exponent on the variable z is
`-3`.

Explanation:

The given equation is:

`(27x^2z)/(-3x^2z^4)`

Simplifying the above equation by simplifying the exponents and the powers, we get

=
`(-9z)/(z^4)`

=
`-9z^(-3)`

Therefore, the exponent on the variable z is
`-3`.
