simplify log_{a}(1/2)

Solution

simplify

lo g_{a} (\frac{1}{2})

Solution

- lo g_{a} (2)

Solution steps

lo g_{a} (\frac{1}{2})

\frac{1}{2} = 2^{- 1}

= lo g_{a} (2^{- 1})

Apply log rule:

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

lo g_{a} (2^{- 1}) = - 1 \cdot lo g_{a} (2)

= - 1 \cdot lo g_{a} (2)

Apply rule:

1 \cdot a = a

= - lo g_{a} (2)
