Answer:

#5.0 times 10^-3 km#

Explanation:

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

#5.0#

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

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

#10^-3#

Therefore # 5.0 times 10^-3#.

Note: If you are converting a number such as #5000# to scientific notation, again express it as a number between #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#
