Let's choose 1.95 x 10^6 and subtract it from 1,845.19:
1,845.19 - 1.95 x 10^6
To subtract two numbers written in scientific notation, we need to make sure their exponents are the same. So, let's convert 1,845.19 to scientific notation:
1,845.19 = 1.84519 x 10^3
Now we can subtract:
1.84519 x 10^3 - 1.95 x 10^6
Since the exponents are the same, we can directly subtract the coefficients:
1.84519 - 1.95 = -0.10481
Therefore,
1,845.19 - 1.95 x 10^6 = -0.10481 x 10^3
We can also write this in standard form:
-0.10481 x 10^3 = -104.81
So, 1,845.19 - 1.95 x 10^6 = -104.81.
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 subtract it from 1,845.19 (or subtract 1,845.19 from the number you choose). Show your work
