Let's choose 1.95 x 10^6 and 2.56 x 10^-2.
When subtracting numbers in scientific notation, we need to make sure that the exponents are the same before subtracting.
First, we need to rewrite 1.95 x 10^6 and 2.56 x 10^-2 with the same exponent. In this case, let's use 10^6.
1.95 x 10^6 = 1.95 x 10^6
2.56 x 10^-2 = 0.0000256 x 10^6 = 2.56 x 10^4
Now that the exponents are the same, we can subtract the numbers:
1.95 x 10^6 - 2.56 x 10^4 = (1.95 - 2.56) x 10^6 = -0.61 x 10^6
So, the result of subtracting 1.95 x 10^6 and 2.56 x 10^-2 is -0.61 x 10^6.
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 two from the scientific numbers from the list and subtract them. Show your work.
