simplify log_{23}(0.2)

Solution

simplify

lo g_{23} (0.2)

Solution

- lo g_{23} (5)

+1

Decimal Notation

- 0.51329 \dots

Solution steps

lo g_{23} (0.2)

0.2 = \frac{2}{10}

= lo g_{23} (\frac{2}{10})

Cancel the numbers:

\frac{2}{10} = \frac{1}{5}

= lo g_{23} (\frac{1}{5})

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

= lo g_{23} (5^{- 1})

Apply log rule:

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

lo g_{23} (5^{- 1}) = - 1 \cdot lo g_{23} (5)

= - 1 \cdot lo g_{23} (5)

Apply rule:

1 \cdot a = a

= - lo g_{23} (5)
