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,......
Convert zero point zero zero zero zero zero zero zero eight seven five from standard form to scientific notation.

eight point seven five times ten to the negative eighth power

eight point seven five times ten to the negative ninth power

eight point seven five times ten to the negative tenth power

eighty−seven point five times ten to the negative ninth power

Convert four billion seven hundred million from standard form to scientific notation.

four hundred seventy times ten to the seventh power

forty−seven times ten to the eighth power

four point seven times ten to the ninth power

forty−seven to the eighth power

Convert one point five times ten to the eighth power from scientific notation to standard form.

fifteen million

one hundred fifty million

one billion five hundred million

fifteen billion

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
