Jika 7 lo g 2 = a dan 2 lo g 3 = b , maka 6 lo g 98 = ...

Jika $^{7} lo g 2 = a$ dan $^{2} lo g 3 = b$ , maka $^{6} lo g 98 = ...$

$fraction numerator a over denominator a plus b end fraction$
$fraction numerator a plus 2 over denominator b plus 1 end fraction$
$fraction numerator a plus 2 over denominator a open parentheses b plus 1 close parentheses end fraction$
$fraction numerator a plus 1 over denominator b plus 2 end fraction$
$fraction numerator a plus 2 over denominator b open parentheses a plus 1 close parentheses end fraction$
