1841 ≈ 1800 (nearest hundred)
964 ≈ 1000 (nearest hundred}
<span>1,841 + 964 </span>≈ 1800 + 1000 = 2800 (Answer B)
Answer:

Step-by-step explanation:
1 n=0
1 1 n=1
1 2 1 n=2
1 3 3 1 n=3
1 4 6 4 1 n=4
1 5 10 10 5 1 n=5
1 6 15 20 15 6 1 n=6
This is where n is the exponent in
.

Now we want to expand:
or we we can rewrite as
.
Let's replace
with
and
with
in the expansion:



Let's simplify a bit:


Answer:20x^4+55x^3+15x^2-2/5x^2
