The population of a city is given as a 3.45 x 10^6 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
To find the sum of the populations of the two cities in scientific notation, we can add the two numbers:
3.45 x 10^6 + 1.3 x 10^5
First, we need to align the numbers so that they have the same exponent:
3.45 x 10^6 + 0.13 x 10^6
Next, we can add the numbers:
(3.45 + 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 first need to convert them into the same exponent form.
The population of the first city is 3.45 x 10^6, and the population of the second city is 1.3 x 10^5.
We can convert 3.45 x 10^6 to the same exponent form as 1.3 x 10^5 by moving the decimal point to the left by one place, resulting in 34.5 x 10^5.
Now, we can add the populations:
34.5 x 10^5 + 1.3 x 10^5 = 35.8 x 10^5
To express the sum in scientific notation, we need to make sure the coefficient is between 1 and 10. Therefore, we can rewrite it as:
3.58 x 10^6
Therefore, the sum of the populations of the two cities is 3.58 x 10^6 in scientific notation.
To find the sum of the populations of the two cities in scientific notation, you can add the numbers in front of the powers of 10 separately.
Given:
Population of the first city = 3.45 x 10^6
Population of the second city = 1.3 x 10^5
Step 1: Add the numbers in front of the powers of 10:
3.45 + 1.3 = 4.75
Step 2: Keep the larger power of 10, which is 10^6 in this case, since it represents the larger population.
Therefore, the sum of the populations of the two cities in scientific notation is 4.75 x 10^6.
