Question

In this problem, you will practice added, subtracting, multiplying, and dividing numbers written in scientific notation. For each part, use the following numbers.
3.2 x 10^4, 1.95 x 10^6, 8.03 x 10^-8, 2.56 x 10^-2, 4.82 x 10^12
Choose one of the scientific numbers from the list and add it to 32.8. Show your work.

Answer 1

Let's choose the scientific number 3.2 x 10^4 and add it to 32.8.

To add these numbers, we need to adjust the scientific notation of 3.2 x 10^4 and 32.8 so that they have the same exponent.

32.8 can be written in scientific notation as 3.28 x 10^1.

Now, we can add the two numbers:

(3.2 x 10^4) + (3.28 x 10^1) = (3.2 + 3.28) x 10^4

Adding the values inside the parentheses:

= 6.48 x 10^4

Therefore, when we add 3.2 x 10^4 to 32.8, the result is 6.48 x 10^4.
