$10^{\log (\frac{x}{10^{- 12}})}$

Step 1

Exponentiation and log are inverse functions.

$\frac{x}{10^{- 12}}$

Step 2

Move $10^{- 12}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$x \cdot 10^{12}$

Step 3

Raise $10$ to the power of $12$ .

$x \cdot 1000000000000$

Step 4

Move $1000000000000$ to the left of $x$ .
