simplify log_{10}(1/5)

Solution

simplify

lo g_{10} (\frac{1}{5})

Solution

- lo g_{10} (5)

+1

Solution steps

lo g_{10} (\frac{1}{5})

\frac{1}{5} = 5^{- 1}

= lo g_{10} (5^{- 1})

Apply log rule:

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

lo g_{10} (5^{- 1}) = - 1 \cdot lo g_{10} (5)

= - 1 \cdot lo g_{10} (5)

Apply rule:

1 \cdot a = a

= - lo g_{10} (5)
