Rewrite as an equation.

$\log_{64} (256) = x$

Rewrite $\log_{64} (256) = x$ in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b$ does not equal $1$ , then $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ .

$64^{x} = 256$

Create expressions in the equation that all have equal bases.

${(2^{6})}^{x} = 2^{8}$

Rewrite ${(2^{6})}^{x}$ as $2^{6 x}$ .

$2^{6 x} = 2^{8}$

Since the bases are the same, then two expressions are only equal if the exponents are also equal.

$6 x = 8$

Solve for $x$ .

$x = \frac{4}{3}$

The variable $x$ is equal to $\frac{4}{3}$ .

Tap for more steps…

Factor $2$ out of $8$ .

$x = \frac{2 (4)}{6}$

Cancel the common factors.

Tap for more steps…

Factor $2$ out of $6$ .

$x = \frac{2 \cdot 4}{2 \cdot 3}$

Cancel the common factor.

$x = \frac{2 \cdot 4}{2 \cdot 3}$

Rewrite the expression.

$x = \frac{4}{3}$

The result can be shown in multiple forms.

Exact Form:

$x = \frac{4}{3}$

Decimal Form:

$x = 1.\overline{3}$

Mixed Number Form:

$x = 1 \frac{1}{3}$
