To write the number 953,000,000 in scientific notation, you express it as a number between 1 and 10 multiplied by a power of 10.
-
Move the decimal point in the number to the left until you have a number between 1 and 10. For 953,000,000, you would move the decimal point 8 places to the left, resulting in 9.53.
-
Count the number of places you moved the decimal point. In this case, it is 8.
-
Write the number in the form \( a \times 10^n \), where \( a \) is the number you obtained (9.53) and \( n \) is the number of places you moved the decimal point (8).
Therefore, in scientific notation, 953,000,000 can be written as:
\[ 9.53 \times 10^8 \]
