First review what you know:

149,598,000 kilometers = 1 AU (astronomical unit)

1000 meters in a kilometer

100 centimeters in a meter

(remember centi means 100 and kilo means 1000)

So 1000*100 = 100,000 centimeters in a kilometer

100,000 x 149,598,000 = 14,959,800,000,000

Now that is a really big number so scientific notation is a good way to display the result (not the rounding up):

1.496x10^13 centimeters in an AU

What is 9.5 AU in CM?

An AU is approximately 150 million kilometers. In scientific notation: 1.5 x 108 km. I see no point in converting that to centimeters, but if you want to do it, you can multiply that number by 100,000 (=105) (1 kilometer = 1000 meters, and 1 meter = 100 cm).
