To compare the numbers 364,879; 463,000; and 436,765 using scientific notation, we first convert each number into scientific notation:
-
364,879: \[ 364,879 = 3.64879 \times 10^5 \]
-
463,000: \[ 463,000 = 4.63 \times 10^5 \]
-
436,765: \[ 436,765 = 4.36765 \times 10^5 \]
Now we compare the coefficients (the numbers in front of \(10^5\)) to determine which number has the least value:
- \(3.64879\) for 364,879
- \(4.63\) for 463,000
- \(4.36765\) for 436,765
Among these coefficients, \(3.64879\) is the smallest.
Therefore, the number with the least value is 364,879.
