$0.625 \frac{1}{10^{18}}$

Step 1.3

Move

10^{18}

$10^{18}$ to the numerator using the negative exponent rule

\frac{1}{b^{n}} = b^{- n}

$\frac{1}{b^{n}} = b^{- n}$ .

0.625 \cdot 10^{- 18}

$0.625 \cdot 10^{- 18}$

0.625 \cdot 10^{- 18}

$0.625 \cdot 10^{- 18}$

Step 2

Move the decimal point in

0.625

$0.625$ to the right by

1

$1$ place and decrease the power of

10^{- 18}

$10^{- 18}$ by

1

$1$ .
