Answer:
C
Step-by-step explanation:
If a number is to the power of a negative number, then it is just that number's reciprocal: e.g. y⁻ˣ = 
Therefore, m⁻² will be m² in the denominator, as n⁻³ will be n³ in the numerator.
That will look like 
.
So, that is C.

Answer: rational
a rational number is a number that can be expressed by a quotient or a fraction
The values that make this statement falser are any in which a and b do not have the same sign.
For instance, if a was equal to 3 and b was equal to -3 than see the results.
|a+b|=
|3+-3|=
|0|= 0
Then see the next equation with the same selections
|a|+|b|
|3|+|-3|
3 + 3 = 6
And this would be true no matter which is the negative, as long as there is one negative and one positive.
