To convert the numbers to scientific notation, we need to move the decimal point until there is only one digit to the left of the decimal.
364,879 is already written in standard form, so it does not need to be converted to scientific notation.
For 463,000, we can move the decimal point 5 places to the left to get 4.63×10⁵.
For 436,765, we can move the decimal point 5 places to the left to get 4.36765×10⁵.
Comparing the numbers in scientific notation, we can see that 4.36765×10⁵ is the smallest value.
Therefore, the correct answer is:
A. 4.36765×10⁵
Compare 364,879; 463,000; and 436,765 using scientific notation. Which number has the least value?
A. 4.36765×10⁵
B. 3.64879×10⁵
C. 364,879
D. 4.63×10⁵

Use scientific notation to compare these numbers: 12,740,876,635; 1,345,763,334; and 12,920,370,000, which has the greatest value?
To compare the numbers using scientific notation, we need to convert them to scientific notation by moving the decimal point so that there is only one digit to the left of the decimal.
For 12,740,876,635, we can move the decimal point 10 places to the left to get 1.2740876635 × 10¹⁰.
For 1,345,763,334, we can move the decimal point 9 places to the left to get 1.345763334 × 10⁹.
For 12,920,370,000, we can move the decimal point 11 places to the left to get 1.292037 × 10¹⁰.
Comparing the numbers in scientific notation, we can see that 1.292037 × 10¹⁰ has the greatest value.
Therefore, the correct answer is:
12,920,370,000 has the greatest value.
For 12,740,876,635, we can move the decimal point 10 places to the left to get 1.2740876635 × 10¹⁰.
For 1,345,763,334, we can move the decimal point 9 places to the left to get 1.345763334 × 10⁹.
For 12,920,370,000, we can move the decimal point 11 places to the left to get 1.292037 × 10¹⁰.
Comparing the numbers in scientific notation, we can see that 1.292037 × 10¹⁰ has the greatest value.
Therefore, the correct answer is:
12,920,370,000 has the greatest value.
