Exercise 47 Page 415

Recall the formula ∑_(i=1)^n 1 = n.

35

Practice makes perfect
Let's start by recalling the formula for this special series. Sum ofn terms of1 ∑_(i=1)^n 1 = nLet's now consider the given series. ∑_(i=1)^(35) 1 Here we have that n = 35. Therefore, to find the desired sum we will substitute 35 for n in the corresponding formula.
∑_(i=1)^n 1 = n
∑_(i=1)^(35) 1 = 35
