The answer is 4.
Step-by-step explanation:
Well, let's break this into pieces.
First, let's work on the first term.
3^8 = 6,561
2^-5 = 1/2^5 = 1/32
9^0 = 1
Multiply all those together, and you get 6,561/32.
Then, if you set that fraction to the power of -2, you get 1,024/43,046,721
Now, let's take the middle term.
2^-2 = 1/4
3^3 = 27
Multiply them together to get 1/108.
Then, set the fraction to the power of 4 to get 1/136,048,896
Next, let's focus on the last term.
3^28 = 22,876,792,454,961
Finally, we have to multiply the terms together.
1,024/43,046,721 · 1/136,048,896 · 22,876,792,454,961
This equals 23,425,835,473,880,000/5,856,458,868,470,016, which can be simplified (quite nicely) to a final answer of 4.
