$\log (x) = - 6$

Step 1

Add $6$ to both sides of the equation.

$\log (x) + 6 = 0$

Step 2

Subtract $6$ from both sides of the equation.

$\log (x) = - 6$

Step 3

Rewrite $\log (x) = - 6$ in exponential form using the definition of a logarithm. If $x$ and $b$ are positive real numbers and $b \neq 1$ , then $\log_{b} (x) = y$ is equivalent to $b^{y} = x$ .

$10^{- 6} = x$

Step 4

Solve for $x$ .

Step 4.2.1

Rewrite the expression using the negative exponent rule $b^{- n} = \frac{1}{b^{n}}$ .

$x = \frac{1}{10^{6}}$

Step 4.2.2

Raise $10$ to the power of $6$ .

$x = \frac{1}{1000000}$
