Evaluate log base 7 of cube root of 49

$\log_{7} (\sqrt[3]{49})$

Step 1

The change of base rule can be used if $a$ and $b$ are greater than $0$ and not equal to $1$ , and $x$ is greater than $0$ .

$\log_{a} (x) = \frac{\log_{b} (x)}{\log_{b} (a)}$

Step 2

Substitute in values for the variables in the change of base formula, using $b = 10$ .

$\frac{\log (\sqrt[3]{49})}{\log (7)}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$\frac{\log (\sqrt[3]{49})}{\log (7)}$

Decimal Form:

$0.\overline{6}$
