Scientific Notation Portfolio
Use this worksheet to record your answers to the Scientific Notation portfolio activities. There are 3 parts, so make sure you scroll down to see all of them. When you are finished, save your worksheet with your answers and submit it for a portfolio grade. By showing your work, we are asking you to write the equation and then solve and write the answer.

Part 1: Use the following numbers.

3.2 ✕ 10^4 1.95 ✕ 10^6 8.03 ✕ 10^-8 2.56 ✕ 10^-2 4.82 ✕ 10^12

Choose two of the scientific numbers from the list and add them. Show your work.

Answer 1

is it this = 1.982 × 10^6 or no

Answer 2

so its not this = 1.982 × 10^6

Answer 3

your positve

Answer 4

Let's choose 3.2 ✕ 10^4 and 1.95 ✕ 10^6.

To add these numbers, we need to make sure they have the same exponent. Let's convert 3.2 ✕ 10^4 to scientific notation with the exponent of 6.

3.2 ✕ 10^4 = 0.32 ✕ 10^5

Now we can add the numbers:

(0.32 ✕ 10^5) + (1.95 ✕ 10^6)

To add these numbers, we can add the coefficients and keep the same exponent:

0.32 + 1.95 = 2.27

So, the sum of 3.2 ✕ 10^4 and 1.95 ✕ 10^6 is 2.27 ✕ 10^6.

Answer 5

Apologies for the mistake. Let's redo the addition.

We have 3.2 × 10^4 and 1.95 × 10^6.

To add these numbers, we need to make sure they have the same exponent. Let's convert 3.2 × 10^4 to scientific notation with the exponent of 6.

3.2 × 10^4 = 0.32 × 10^5

Now we can add the numbers:

(0.32 × 10^5) + (1.95 × 10^6)

To add these numbers, we can add the coefficients and keep the same exponent:

0.32 + 1.95 = 2.27

Therefore, the sum of 3.2 × 10^4 and 1.95 × 10^6 is 2.27 × 10^6.

Thank you for catching the error!

Answer 6

Apologies for any confusion caused. You are correct, the sum of 3.2 × 10^4 and 1.95 × 10^6 is 1.982 × 10^6. Thank you for catching that mistake.
