simplify log_{10}(0.4)

Solution

simplify

lo g_{10} (0.4)

Solution

2 lo g_{10} (2) - 1

+1

Decimal Notation

- 0.39794 \dots

Solution steps

lo g_{10} (0.4)

0.4 = \frac{4}{10}

= lo g_{10} (\frac{4}{10})

Apply log rule:

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

lo g_{10} (\frac{4}{10}) = lo g_{10} (4) - lo g_{10} (10)

= lo g_{10} (4) - lo g_{10} (10)

lo g_{10} (4) = 2 lo g_{10} (2)

lo g_{10} (10) = 1

= 2 lo g_{10} (2) - 1
