simplify log_{25}(0.8)

Solution

simplify

lo g_{25} (0.8)

Solution

lo g_{5} (2) - \frac{1}{2}

+1

Decimal Notation

- 0.06932 \dots

Solution steps

lo g_{25} (0.8)

0.8 = \frac{8}{10}

= lo g_{25} (\frac{8}{10})

Cancel

\frac{8}{10} : \frac{4}{5}

= lo g_{25} (\frac{4}{5})

Apply log rule:

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

lo g_{25} (\frac{4}{5}) = lo g_{25} (4) - lo g_{25} (5)

= lo g_{25} (4) - lo g_{25} (5)

lo g_{25} (4) = lo g_{5} (2)

lo g_{25} (5) = \frac{1}{2}

= lo g_{5} (2) - \frac{1}{2}
