Move the decimal after the number 1.
O Move the decimal after the number 9.
O Drop all of the zeroes following the number 9.
O Count the number of positions to move the decimal place.

Answer 1

Answer:

i think it is Move the decimal after the number 1.

Step-by-step explanation:

it the text it says

"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km? As you read the information in this lesson, challenge yourself by converting the large numbers into scientific notations."

Answer 2

Awnser:

(C) Move the decimal after the number 1.

Step-by-step explanation:

The correct answer is Move the decimal after the number 1. The first step in converting a large number to a scientific notation is to determine the coefficient, which is always greater than 1 and less than 10.
