2. Evaluate each of the following sums. These same sums will be seen again later in this course in the context of computing the area between a function and the m-axis. (a) :3: (53' + 4) (Note that your answer should be a positive numeric value.) j=1 (b) 3;; [(1+%)24(1+%) +5 \" 4 43' 2 43' C)ZR[(;)_;+1 j=1 https: wa . desmos . com/ca1cu1ator/pthrp1x28 (Note that your answer should be a positive numeric value.) (Note that your answer should be an expression in the variable in.) 3. Write the summation as an equivalent summation with the index of summation starting at k = 0. (a) Z (k1)1(.n _k)!p (1-19)\"- (b) 5 (3)
