Let's choose the number 3.2 x 10^4 and add it to 32.8.
First, we need to convert 32.8 to scientific notation. Since 32.8 is already in decimal form, we can express it as 3.28 x 10^1.
Now we can add 3.2 x 10^4 and 3.28 x 10^1:
3.2 x 10^4 + 3.28 x 10^1 = 3.2 x 10000 + 3.28 x 10 = 32000 + 32.8
To combine the two numbers, the exponents of 10 need to be the same, so we need to rewrite 32000 as a number multiplied by 10 raised to an exponent:
32000 = 3.2 x 10000 = 3.2 x 10^4
Now we can add the numbers:
3.2 x 10^4 + 3.28 x 10^1 = 3.2 x 10^4 + 3.2 x 10^1 = 3.2 x 10^4 + 3.2 x 10^4 = 6.4 x 10^4
Therefore, when we add 3.2 x 10^4 to 32.8, we get 6.4 x 10^4.
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
