$5.0 \times 10^{- 3} k m$ $5.0 times 10^-3 km$

Explanation:

Express $0.005$ $0.005$ as a number between $1 and 10 .$ $1and 10.$

$5.0$ $5.0$

Count how many places, you moved the decimal point to do this.

It was moved $3$ $3$ places to the right which gives you $- 3$ $-3$ as the power for $10$ $10$ .

$10^{- 3}$ $10^-3$

Therefore $5.0 \times 10^{- 3}$ $5.0 times 10^-3$ .

Note: If you are converting a number such as $5000$ $5000$ to scientific notation, again express it as a number between $1 and 10$ $1 and 10$ but because you have moved the decimal point to the left, the power of 10 is positive.

$5.0 \times 10^{3}$ $5.0 times 10^3$
