Answer:
An expression equivalent to negative four raised to the fourth power divided by negative four raised to the second power is:
(-4)^4 / (-4)^2
To simplify this expression, you can use the properties of exponents:
(-4)^4 / (-4)^2 = (-4)^(4 - 2) = (-4)^2 = 16
So, the equivalent expression is 16.
