Bab Sigma
Matematika SMA Kelas X

₅
∑  (2^k - 2)
k = 1
= (2^1 - 2) + (2^2 - 2) + (2^3 - 2) + (2^4 - 2) + (2^5 - 2)
= 2 - 2 + 4 - 2 + 8 - 2 + 16 - 2 + 32 - 2
= 0 + 2 + 6 + 14 + 30
= 52

jawabannya D

(2¹ - 2) + (2² - 2) + (2³ - 2) + (2⁴ - 2) + (2⁵ - 2)
= 0 + 2 + 6 + 14 + 30
= 52     ( D )

semoga jelas dan membantu ya
