⁷log 2 = a ↔ ²log 7 = [tex] \frac{1}{a} [/tex]
²log 3 = b

[tex] ^6 \log 98 = \frac{ ^2 \log 98 }{ ^2 \log 6 } \\
= \frac{ ^2 \log 7^2 \times 2 }{ ^2 \log 3 \times 2 } \\
= \frac{2 \ ^2 \log 7 + ^2 \log 2}{ ^2 \log 3 + ^2 \log 2} \\
= \frac{ \frac{2}{a} + 1}{b + 1} \ [ \times \ a] \\
= \frac{a + 2}{a(b + 1)} [/tex]
