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 subtract it from
1,845.19 (or subtract 1,845.19 from the number you choose). Show your
work.

Answer 1

Let's choose the number 3.2 x 10^4.
To subtract it from 1,845.19, we need to convert 1,845.19 to scientific notation.
1,845.19 = 1.84519 x 10^3

Now, we can subtract 3.2 x 10^4 - 1.84519 x 10^3:

(3.2 x 10^4) - (1.84519 x 10^3)
= 3.2 x 10^4 - 1.84519 x 10^3

Since both numbers have the same power of 10 (10^4), we can subtract their coefficients:
(3.2 - 1.84519) x 10^4
= 1.35481 x 10^4
