Answer:
A
Step-by-step explanation:
18=1×18=18
2×9=18
. 3×6=18
6×3=18
9×2=18
18×1=18
30=1×30=30
2×15=30
3×10=30
5×6=30
6×5=30
10×3=30
15×2=30
30×1=30
Let's deal with each factor in the numerator individually first: when evaluating the power of a power, you have to multiply the exponents: 
So, we have
^{-\frac{1}{2}} = 3^{2\cdot(-\frac{1}{2})} = 3^{-1},\quad (9^4)^{-1} = 9^{-4}](https://tex.z-dn.net/?f=%20%5Btex%5D%283%5E2%29%5E%7B-%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%203%5E%7B2%5Ccdot%28-%5Cfrac%7B1%7D%7B2%7D%29%7D%20%3D%203%5E%7B-1%7D%2C%5Cquad%20%289%5E4%29%5E%7B-1%7D%20%3D%209%5E%7B-4%7D)
Now remember that 
and 
to rewrite the expression as
Now use the rules
to conclude
