simplify log_{b}(1/18)

Solution

simplify

lo g_{b} (\frac{1}{18})

Solution

- lo g_{b} (18)

Solution steps

lo g_{b} (\frac{1}{18})

\frac{1}{18} = 1 8^{- 1}

= lo g_{b} (1 8^{- 1})

Apply log rule:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x), x > 0

lo g_{b} (1 8^{- 1}) = - 1 \cdot lo g_{b} (18)

= - 1 \cdot lo g_{b} (18)

Apply rule:

1 \cdot a = a

= - lo g_{b} (18)
