The sum of the populations of the two cities can be found by adding the numbers in front of the 10, and keeping the same power of 10.
(3.45 * 10^6) + (1.3 * 10^5)
To add the numbers in front of the 10, we can convert both numbers to the same power of 10.
3.45 * 10^6 = 34.5 * 10^5
1.3 * 10^5 = 13 * 10^5
Now we can add the numbers:
34.5 * 10^5 + 13 * 10^5
Adding the numbers in front of the 10 gives: 34.5 + 13 = 47.5
Keeping the same power of 10 (10^5) gives the final result as:
47.5 * 10^5
So, the sum of the populations of the two cities in scientific notation is 47.5 * 10^5.
(3.45 * 10^6) + (1.3 * 10^5)
To add the numbers in front of the 10, we can convert both numbers to the same power of 10.
3.45 * 10^6 = 34.5 * 10^5
1.3 * 10^5 = 13 * 10^5
Now we can add the numbers:
34.5 * 10^5 + 13 * 10^5
Adding the numbers in front of the 10 gives: 34.5 + 13 = 47.5
Keeping the same power of 10 (10^5) gives the final result as:
47.5 * 10^5
So, the sum of the populations of the two cities in scientific notation is 47.5 * 10^5.
