Step 1.1

Group coefficients together and exponents together to divide numbers in scientific notation.

$(\frac{0.4}{50}) (\frac{1}{10^{- 6}})$

Step 1.2

Divide $0.4$ by $50$ .

$0.008 \frac{1}{10^{- 6}}$

Step 1.3

Move $10^{- 6}$ to the numerator using the negative exponent rule $\frac{1}{b^{- n}} = b^{n}$ .

$0.008 \cdot 10^{6}$

Step 2

Move the decimal point in $0.008$ to the right by $3$ places and decrease the power of $10^{6}$ by $3$ .

$8 \cdot 10^{3}$

Step 3

The result can be shown in multiple forms.

Scientific Notation:

$8 \cdot 10^{3}$
