The population of a city is given as 3.45×10^6. A nearby city has a population of 1.3×10^5. What is the sum of the populations of the two cities in scientific notation?(1 point)
The population of the first city is 3.45×10^6 and the population of the second city is 1.3×10^5.
To find the sum, we need to add the two population values together.
First, we must ensure that both numbers have the same power of 10.
We can rewrite 1.3×10^5 as 0.13×10^6.
Now, we can add the two populations:
(3.45×10^6) + (0.13×10^6) = 3.58×10^6
Therefore, the sum of the populations of the two cities is 3.58×10^6.
To find the sum of the populations of the two cities in scientific notation, we can add the numbers before the exponent and keep the same exponent.
The population of the first city is 3.45×10^6, and the population of the second city is 1.3×10^5.
Adding the numbers before the exponent, we get:
3.45 + 1.3 = 4.75
Keeping the same exponent, the sum of the populations in scientific notation is:
4.75×10^6
To find the sum of the populations of the two cities in scientific notation, you need to add the numbers in front of the powers of 10 separately and then write the result in scientific notation.
The population of the first city is given as 3.45×10^6.
The population of the second city is given as 1.3×10^5.
To add these two numbers, we need to make sure their exponents (powers of 10) are the same. In this case, we can convert the second number to have the same exponent as the first number.
To convert the population of the second city, we can rewrite it as follows:
1.3×10^5 = 0.13×10^6
Now that both numbers have the same exponent of 10, we can add them:
3.45×10^6 + 0.13×10^6 = (3.45 + 0.13)×10^6 = 3.58×10^6
Therefore, the sum of the populations of the two cities in scientific notation is 3.58×10^6.
