simplify log_{243}(3)

Solution

simplify

lo g_{243} (3)

Solution

\frac{1}{5}

+1

Solution steps

lo g_{243} (3)

Factor the number:

243 = 3^{5}

= lo g_{3^{5}} (3)

Apply log rule:

lo g_{a^{b}} (x) = \frac{1}{b} lo g_{a} (x), a > 0

lo g_{3^{5}} (3) = \frac{1}{5} lo g_{3} (3)

= \frac{1}{5} lo g_{3} (3)

Apply log rule:

lo g_{a} (a) = 1

lo g_{3} (3) = 1

= \frac{1}{5} \cdot 1

Multiply the numbers:

\frac{1}{5} \cdot 1 = \frac{1}{5}

= \frac{1}{5}
