Los Angeles has a population of 3,971,883 people. Estimate the population as a single digit number times a power of 10.
To estimate the population of Los Angeles as a single digit number times a power of 10, we need to move the decimal point so that there is one non-zero digit to the left of the decimal point.
The population of Los Angeles is 3,971,883.
We can move the decimal point two places to the left to get a single digit in the thousands place: 39.71883
Now we can round 39.71883 to the nearest whole number: 40.
Thus, the estimate of the population of Los Angeles as a single digit number times a power of 10 is approximately 40 x 10^6.
