Solution

simplify

lo g_{2} (\frac{1}{3})

Solution

- lo g_{2} (3)

+1

Decimal Notation

- 1.58496 \dots

Solution steps

lo g_{2} (\frac{1}{3})

\frac{1}{3} = 3^{- 1}

= lo g_{2} (3^{- 1})

Apply log rule:

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

lo g_{2} (3^{- 1}) = - 1 \cdot lo g_{2} (3)

= - 1 \cdot lo g_{2} (3)

Apply rule:

1 \cdot a = a

= - lo g_{2} (3)
