What is 4.82x10^12 - 1.95x10^6, as a scientific notation, show work.

Answer 1

To subtract these two numbers in scientific notation, we need to ensure that the exponents are the same.

Rewriting 4.82x10^12 in scientific notation with an exponent of 6 gives:
4.82x10^12 = 4.82x10^(12-6) = 4.82x10^6

Now, we can perform the subtraction:

4.82x10^12 - 1.95x10^6 = 4.82x10^6 - 1.95x10^6

To subtract the numbers, we need to make sure that the bases (4.82 and 1.95) are the same. Let's rewrite 1.95 in scientific notation with an exponent of 6:

1.95x10^6 = 1.95x10^(6-6) = 1.95x10^0

Now the bases are the same and the subtraction can be carried out:

4.82x10^6 - 1.95x10^6 = (4.82 - 1.95)x10^6 = 2.87x10^6

Therefore, 4.82x10^12 - 1.95x10^6 in scientific notation is 2.87x10^6.
