$10^{a} = 8$

Step 1

Take the base $10$ logarithm of both sides of the equation to remove the variable from the exponent.

$\log (10^{a}) = \log (8)$

Step 2

Expand the left side.

Step 2.1

Expand $\log (10^{a})$ by moving $a$ outside the logarithm.

$a \log (10) = \log (8)$

Step 2.2

Logarithm base $10$ of $10$ is $1$ .

$a \cdot 1 = \log (8)$

Step 2.3

Multiply $a$ by $1$ .

$a = \log (8)$

Step 3

The result can be shown in multiple forms.

Exact Form:

$a = \log (8)$

Decimal Form:

$a = 0.90308998 \dots$
