I need this done quickly please. Would appreciate it.

Euler found the sum of the p-series with p = 4:
ζ(4)=∞, n=1 of (1/n^4) = pi^4 / 90

Use Euler's result to find the sum of the series.

∞, k=7 OF 1 / (k-4)^4

Let S be Sum (k=7,infinity, 1 / (k-4)^4).

S = Sum (n=3,infinity, 1 / n^4)
(rename the variable k-4 to n)

S = Sum (k=1,infinity, 1 / n^4) - 1/1^4 - 1/2^4
(considering the 2 missing terms)

S = pi^4 / 90 - 1 - 1/16
