nomor 2 bagian a sama b yah kak

2^log p, 2^log 2p, 2^log 4p

b = U2 - U1
b = 2^log 2p - 2^log p
b = 2^log 2p/p
b = 2^log 2
b = 1

t, t + 1, t + 2

b = U2 - U1
b = 1/3 phi r^2 (t + 1) - t
b = 1

atau

b = U2 - U1
b = 1/3 phi r^2 (t + 1) - 1/3 phi r^2 t
b = 1/3 phi r^2 (t + 1 - t)
b = 1/3 phi r^2 (1)
b = 1

semoga membantu##
