In this problem, you will practice adding, subtracting, multiplying, and dividing
numbers written in scientific notation. For each part, use the following numbers.
a. Choose two of the scientific numbers from the list and add them. Show your
work.
Unfortunately, you have not provided the list of scientific numbers to choose from. Without the numbers, it is not possible to provide a specific solution.
Please provide the list of scientific numbers so that I can assist you further.
To add two numbers written in scientific notation, you need to make sure the exponents are the same. Here are two scientific numbers from the list:
Number 1: 3.5 x 10^4
Number 2: 2.2 x 10^2
To add these two numbers, first, we need to make their exponents the same. We can do this by moving the decimal point in the number with the smaller exponent to the right or left until it has the same exponent as the other number.
Let's move the decimal point in Number 2 to the right two places, so it becomes 0.022 x 10^4.
Now that the exponents are the same, we can add the two numbers:
3.5 x 10^4 + 0.022 x 10^4 = (3.5 + 0.022) x 10^4 = 3.522 x 10^4
So, the sum of the two numbers is 3.522 x 10^4.
To add two numbers written in scientific notation, you need to have both numbers expressed in the same power of 10. If they have different powers of 10, you will need to adjust one or both of the numbers so that they have the same power of 10. Here's how you can add two scientific numbers:
Step 1: Identify the powers of 10 for both numbers.
Step 2: Determine the larger power of 10 and the corresponding number.
Step 3: Adjust the other number by shifting the decimal point to match the power of 10 of the larger number.
Step 4: Add the adjusted numbers.
Step 5: Simplify the result, if needed, by adjusting the number to scientific notation.
Let's say we have two scientific numbers: 3.2 x 10^4 and 1.5 x 10^3.
Step 1: Powers of 10
The first number has a power of 10 of 4, while the second number has a power of 10 of 3.
Step 2: Larger power of 10
The larger power of 10 is 4, with a corresponding number of 3.2.
Step 3: Adjust the second number
To match the power of 10 of the first number, we need to move the decimal point in the second number one place to the right. This gives us 15 x 10^3.
Step 4: Add the adjusted numbers
Now we can add the adjusted numbers:
3.2 x 10^4 + 15 x 10^3 = 3.2 x 10^4 + 1.5 x 10^4 = 4.7 x 10^4
Step 5: Simplify the result
If needed, we can adjust the result to scientific notation. In this case, the result is already in scientific notation, so no further adjustments are necessary.
So, the sum of 3.2 x 10^4 and 1.5 x 10^3 is 4.7 x 10^4.
