simplify log_{\sqrt[3]{5}}(25)

Solution

simplify

Solution steps

Apply radical rule:

= lo g_{5^{\frac{1}{3}}} (25)

Apply log rule:

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

lo g_{5^{\frac{1}{3}}} (25) = \frac{1}{\frac{1}{3}} lo g_{5} (25)

= \frac{1}{\frac{1}{3}} lo g_{5} (25)

Factor the number:

25 = 5^{2}

= \frac{1}{\frac{1}{3}} lo g_{5} (5^{2})

Apply log rule:

lo g_{a} (a^{b}) = b

lo g_{5} (5^{2}) = 2

= \frac{1}{\frac{1}{3}} \cdot 2

\frac{1}{\frac{1}{3}} \cdot 2 = 6

= 6
