hi, i have a telescoping problem. i looked up the definition of "telescoping" and found as follows:
when each term of a sum cancels part of the next term, leaving only portions of the first and last terms at them end the sum is said to "telescope."
So, I have to evaluate the telescoping sum of:
the summation of (a to the base of k) - (a to the base of k-1) from k=1 to n
any tips would be appreciated thanks in advance!!
