2] b = (U8 - U4)/(8 - 4)
b = (172.000 - 30.000)/4
b = 35.500

U18 = U8 + 10b
U18 = 172.000 + 10 . 35.500
U18 = 172.000 + 355.000
U18 = Rp 527.000,00

3] ^ = pangkat

p = (⁴log 3 . ⁵log 16)/(⁷log 2 . ⁵log 7)
p = (⁴log 16 . ⁵log 3) / (⁷log 7 . ⁵log 2)
p = 2 . ²log 3
²log 3 = p/2

⁸¹log 8 
= ^(3⁴)log 2³
= (3/4) . ³log 2
= 3/4 . 1/(²log 3)
= 3/(p/2)
= 6/p
