Question

How many centimeters are there in `1.23 * 10^-6` kilometers?

Answer 1

`0.123` centimeters

Explanation:

Each kilometer has `1000` meters and each meter has `100` centimeters.

Hence each kilometer has `1000xx100=100000=10^5` centimeters.

Therefore, `1.23xx10^(-6)` kilometer will have

`1.23xx10^(-6)xx10^5=1.23xx10^(-6+5)=1.23xx10^(-1)` or `0.123` centimeters
