Answer» n 1:-We see that,and,Adding (1) and (2),Hence the remainder is 0.Solution 2:-Given,We need to FIND the remainder obtained on DIVIDING this number by 49.Since 6 = 7 - 1 and 8 = 7 + 1,By binomial expansion,We see that for every whole number k,So we can avoid all terms having odd value of r (since they are zero each) and only consider the terms having even value of r, then the sum becomes,[The limit changes such that r = 0 for k = 0 and r = 202 for k = 0. Since r = 203 is odd, the term having this value of r is zero.]Since the EXPONENT of 7, 201 - 2k ≥ 0 ⇒ k ≤ 100, we take the term having k = 101 out of the sum.Taking Hence the remainder is 0.
