I'm not sure how to get from point A to point B. It seems simple enough, but I'm just not seeing it!

2. Relevant equations

point A:

[tex] \frac{81}{n^4} \ [\frac{n(n+1)}{2}]^2 \ - \ \frac{54}{n^2} \ [\frac{n(n+1)}{2}] [/tex]

point B:

[tex] \frac{81}{4} \ (1 + \frac{1}{n})^2 \ - \ 27(1 + \frac{1}{n}) [/tex]

3. The attempt at a solution

I'm honestly at a loss on this simple problem, however sad that may seem.
