The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.
4.8 x 10 = 48
4.8 x 10 x 10 = 48 x 10 = 480
Each time you multiply by another 10, the decimal point moves one more time.
The expression says you're going to multiply by 10 five times in a row. So that will move the decimal point 5 places to the right.
So what do you get if you move the decimal in 4.8 five places to the right?
