- lo g_{10} (0.015)

0.015 = \frac{15}{1000}

= - lo g_{10} (\frac{15}{1000})

Wende die log Regel an:

lo g_{a} (\frac{x}{y}) = lo g_{a} (x) - lo g_{a} (y)

- lo g_{10} (\frac{15}{1000}) = - (lo g_{10} (15) - lo g_{10} (1000))

= - (lo g_{10} (15) - lo g_{10} (1000))

lo g_{10} (1000) = 3

= - (lo g_{10} (15) - 3)

Wende das Distributivgesetz an:

- (a - b) = - a + b

- (lo g_{10} (15) - 3) = - lo g_{10} (15) + 3

= - lo g_{10} (15) + 3
