Jawaban A. [tex] ^2 \log 2 + ^2 \log 3 - ^2 \log 6 + ^2 \log 8 \\ = ^2 \log (\frac{2 \times 3 \times 8}{6})\\ = ^2 \log 8 = ^2 \log 2^3 = 3 [/tex] Jawaban B. [tex] ^3 \log 729 + ^3 \log 9 \\ = ^3 \log 3^5 + ^3 \log 3^2 \\= 5 + 2 = 7 [/tex]
Jawaban C [tex] ^5 \log x = 4 \\ x = 5^4 = 625 [/tex] Jawaban D [tex] ^2 \log x = -3 \\ x = 2^{-3} = \frac{1}{8} [/tex]
