Question

The value of :
$log_{0.2}(625)$
​

Answer 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.

$log \: a(x) = \frac{log \: b(x)}{log \: b(a)}$

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

$\frac{log(625)}{log(0.2)}$

The result can be shown in multiple forms.

Exact Form:

$\frac{log(625)}{log(0.2)}$

Decimal Form:

−4
