The basic idea is that multiplying by 10 just moves the decimal point one place to the right. It makes the number bigger.
9.3 x 10 = 93
9.3 x 10 x 10 = 93 x 10 = 930
Each time you multiply by another 10, the decimal point moves one more time.
10^4 says you're going to multiply by 10 four times in a row. So that will move the decimal point 4 places to the right.
So what do you get if you move the decimal in 9.3 four places to the right?
Answer:
9300
