Default Pre-Calc Problem

Write the sum using sigma notation

(radical 1)/1^4 + (radical 2)/2^4 + (radical 3)/3^4 ....+ (radical n)/n^4


I already tried radical n/n^4 as the formula and it says it is wrong


can someone help explain how you got the answer?

What is the start number (i=?). If it starts at at a number other than 1, it would be different.

i.e: if i=0 the summation would be radical(n-1)/(n-1)^4

If it starts at 1, your answer would be right though.
