1)
8 zeros total.
Answer: 8,75 * 10^-8 (So the first choice)
2)
Positive so it would be ^9 power with 8 zeros.
4.7 * 10^9 (So the third choice)
3)
positive ^8 power means 7 zeros following the 1.5
1,500,000,00
150,000,000 (Second choice)

1. 0.0000000875
The answer need t be 8.75 x 10^? To change the question mark into an exponent, count the number of places that the decimal point moves. By this count it is found that the decimal point moves -8 places, since it is moving to the right, therefore the notation is:
8.75 x 10^-8
2. 4,700,000,000.
In the same manner count the positions the decimal point movies. Since it is moving the left this time, 10 places, the exponent is positive and the notation is:
4.7 x 10^10
3. In this example, follow the same rule, but in this case the number is in scientific notation. Since the number is greater than 1, the decimal point needs to move to the left 8 places, adding 7 zeros after the 5, or:
150,000,000

1) .0000000875=8.75x10^8 You move the decimal to the right 8 times.
2)4,700,000,000=4.7x10^9 You move the decimal to the left 9 times.
3) 1.5x10^8= 150,000,000 you add 7 zeros
2)4,700,000,000=4.7x10^9 You move the decimal to the left 9 times.
3) 1.5x10^8= 150,000,000 you add 7 zeros
