Well, since we know the remainder is 5, We can see that x³+30x-c-5 when divided by x-5 leaves no remainder at all.

Given this, we can use knowledge to see that:

(x-5)(x²+5x+55) is equal to x³+30x-c-5.

We can multiply 55 and -5 to get -275, so c is 270.

BTW THIS WAS AN EDIT, THE ANSWER FOR C is 270 NOT -270!!!

The function is x²+1, and the product of the 97th term and the 98th term would be

This "n" would equal:

\(\sqrt{(97^2+1)(98^2+1)-1}\)

\(= \)\(\sqrt{97^298^2+98^2+97^2}\)

\(=\)\(\sqrt{90364036+9604+9409}\)

\(= \)\(\sqrt{90383049}\)

\(=\)\(9507\)
