Question

Nilai x yang memenuhi untuk log x = 1/3 log 8 + log 9 - 1/3 log 27 adalah....
a.8
b.6
c.4
d.2
e.1

Answer 1

Log x = log8^(1/3) + log 9 - log27^(1/3)
log x = log2 + log 9 - log3
log x = log(2.9/3)
log x = log 6
x = 6 (b)

Answer 2

Log x = log8^(1/3) + log 9 - log27^(1/3)
log x = log2 + log 9 - log3
log x = log(2.9/3)
log x = log 6
x = 6 (b)
