the population of a city is given as 3.45 x 10^6. A nearby city has a population of 1.3 x 10^5. What is the sum of the populations of the two cities in scientific notation? (1 point)
To find the sum of the populations of the two cities in scientific notation, we add the numbers and keep the same power of 10.
3.45 x 10^6 + 1.3 x 10^5 = 3.45 x 10^6 + 0.13 x 10^6 = 3.58 x 10^6
Therefore, the sum of the populations of the two cities in scientific notation is 3.58 x 10^6.
To find the sum of the populations of the two cities in scientific notation, we can simply add the two numbers and then express the result in scientific notation.
The population of the first city is given as 3.45 x 10^6.
The population of the second city is given as 1.3 x 10^5.
To add these two numbers, we need to align the decimal places.
3.45 x 10^6 + 1.3 x 10^5 = (3.45 x 10^6) + (0.13 x 10^6)
Next, we can add the two numbers:
3.45 x 10^6 + 0.13 x 10^6 = 3.58 x 10^6
So, the sum of the populations of the two cities in scientific notation is 3.58 x 10^6.
To find the sum of the populations of the two cities in scientific notation, you can simply add the numbers before the exponent and keep the common power of 10.
For the first city, the population is given as 3.45 x 10^6, which means the number before the exponent is 3.45.
For the second city, the population is given as 1.3 x 10^5, which means the number before the exponent is 1.3.
Now, add the numbers before the exponent: 3.45 + 1.3 = 4.75.
Since both populations are in scientific notation, with a power of 10, the common power of 10 will be 10^6.
Therefore, the sum of the populations of the two cities in scientific notation is 4.75 x 10^6.
