-(1/3)^0 = -1

(-9)^0 = 1

Step-by-step explanation:

Step 1:

Let us consider the first expression  as -(1/3)^0

In general, [tex]X^{n-n} = X^{n} / X^{n} = X^{0}[/tex] = 1      

By applying the same logic here,  

[tex]- ((1/3)^{3} / (1/3) ^{3}) = -(1)[/tex]

Step 2:

Let us consider the first expression  as (-9)^0

In general, [tex]X^{n-n} = X^{n} / X^{n} = X^{0}[/tex] = 1      

By applying the same logic here,  

[tex]((-9)^{3} / (-9)^{3}) = 1[/tex]
